Method For Studying A Sample And Optical Interferometer For Doing The Same

View page
US Patent:
6992776, Jan 31, 2006
Filed:
Feb 14, 2003
Appl. No.:
10/367396
Inventors:
Felix I. Feldchtein - Mayfield Village OH, US
Paul G. Amazeen - New Castle NH, US
Grigory V. Gelikonov - Nizhny Novgorod, RU
Valentin M. Gelikonov - Nizhny Novorod, RU
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G01B 9/02
US Classification:
356479, 356497
Abstract:
The present invention relates to the study of internal structure of objects by optical means. The invention presents a bi-directional sampling optical path for the low coherent optical radiation directed to the sample, i. e. a bi-directional sampling arm, and two unidirectional reference beams directed along a reference path designed as a loop. One of the reference beams propagates clockwise and the other propagates counterclockwise in the reference loop. The beam splitters non-reciprocal or polarization-dependent and by placing polarization-changing elements between the beam splitters and/or into the sampling arm and the reference loop. Thus the developed method and optical interferometer make possible to ensure highly efficient use of optical source power together with optimal signal-to-noise ratio for a given optical source power and are simple and cost effective.

US Patent:
7227629, Jun 5, 2007
Filed:
Jun 15, 2005
Appl. No.:
11/152936
Inventors:
Felix I. Feldchtein - Cleveland OH, US
J. Lloyd Breedlove - Mooresville NC, US
Stephanie A. S. Harrington - Mentor OH, US
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G01J 1/10
US Classification:
3562431, 600310, 600331
Abstract:
An optical measurement device calibration tool includes an optical probe suitable for calibrating various optical imaging devices, for example, low coherence reflectometers and optical coherence tomography devices. In a preferred embodiment the calibration tool comprises a container containing a calibration substance with stable optical scattering and absorption properties. The calibration substance includes a gel, paste or grease substance and is covered a protective seal, which is at least partially transparent providing optical contact between the optical probe and the calibration substance. The protective seal is covered with a viscous complementary material. Another protective seal made at least partially removable is placed above the viscous complementary material and may serve as a cover for the container. The calibration tool maintains the advantages of calibration tools using liquids and solid states as calibration substance and is more cost-effective and more convenient for calibrating optical measuring devices such as in medical applications.

Optical Fiber Lateral Scanner For A Miniature Optical Fiber Probe

View page
US Patent:
7242826, Jul 10, 2007
Filed:
Jun 15, 2005
Appl. No.:
11/152934
Inventors:
Sergey M. Piyevsky - Orange Village OH, US
Felix I. Feldchtein - Cleveland OH, US
Grigory V. Gelikonov - Nizhny Novgorod, RU
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G02B 6/26
US Classification:
385 16, 385 25
Abstract:
The present invention relates to an optical fiber magnetic scanning arrangement for a miniature optical fiber probe and can be applied for optical beam delivery in various optical imaging techniques. The arrangement is of the type where an optical fiber is rigidly fixed to a current conductor and serving as a flexible cantilever with a capability for the distal part of the optical fiber of being deflected in a direction substantially orthogonal to its own axis. New designs of the magnetic system are less critical to the shape and dimensional tolerances of scanner elements and assembly. These designs provide a potential for a less difficult assembly process and for further miniaturization. According to one aspect of the invention the permanent magnet system includes at least a first permanent magnet with a magnetization direction that is substantially aligned with the own axis of the optical fiber. The current conductor loop is placed adjacent to the one of the end faces of the first permanent magnet. According to another aspect of the invention the permanent magnet system includes at least a first permanent magnet piece with a magnetization direction that is substantially orthogonal to the own axis of the optical fiber.

Common Path Frequency Domain Optical Coherence Reflectometer And Common Path Frequency Domain Optical Coherence Tomography Device

View page
US Patent:
7426036, Sep 16, 2008
Filed:
Jul 10, 2006
Appl. No.:
11/456414
Inventors:
Felix I. Feldchtein - Cleveland OH, US
Grigory V. Gelikonov - Nizhny Novgorod, RU
Assignee:
Imalux Corporation - Cleveland CO
International Classification:
G01B 9/02
G01B 11/02
US Classification:
356479, 356497
Abstract:
Common path frequency domain optical coherence reflectometry/tomography devices with an additional interferometer are suggested. The additional interferometer offset is adjusted such, that it is ether less than the reference offset, or exceeds the distance from the reference reflector to the distal boundary of the longitudinal range of interest. This adjustment allows for relieving the requirements to the spectral resolution of the frequency domain optical coherence reflectometry/tomography engine and/or speed of the data acquisition and processing system, and eliminates depth ambiguity problems. The new topology allows for including a phase or frequency modulator in an arm of the additional interferometer improving the signal-to-noise ratio of the devices. The modulator is also capable of substantially eliminating mirror ambiguity, DC artifacts, and autocorrelation artifacts. The interference signal is produced either in the interferometer or inside of the optical fiber probe leading to the sample.

Common Path Frequency Domain Optical Coherence Reflectometry/Tomography Device

US Patent:
7428053, Sep 23, 2008
Filed:
Oct 9, 2006
Appl. No.:
11/539719
Inventors:
Felix I. Feldchtein - Cleveland OH, US
Grigory V. Gelikonov - Nizhny Novgorod, RU
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G01B 9/02
G01B 11/02
US Classification:
356479, 356497
Abstract:
Common path frequency domain optical coherence reflectometry/tomography devices include a portion of optical fiber with predetermined optical properties adapted for producing two eigen modes of the optical radiation propagating therethrough with a predetermined optical path length difference. The two replicas of the optical radiation outgoing from the portion of the optical fiber are then delivered to an associated sample by an optical fiber probe. The tip of the optical fiber serves as a reference reflector and also serves as a combining element that produces a combination optical radiation by combining an optical radiation returning from the associated sample with a reference optical radiation reflected from the reference reflector. The topology of the devices allows for registering a cross-polarized or a parallel-polarized component of the optical radiation reflected or backscattered from the associated sample. Having the optical path length difference for the two eigen modes of the optical radiation (which is an equivalent of an interferometer offset in previously known devices) differ from the reference offset in the devices of the present invention allows for relieving the requirements to the spectral resolution of the FD OCT engine and/or data acquisition and processing system, and substantially eliminates depth ambiguity problems.

Felix Isaakovich Feldchtein - Cleveland OH, US
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G01B 9/02
US Classification:
356479, 356497, 25022719, 25022727
Abstract:
The invention relates to studies of internal structures of objects with the aid of optical means. According to the invention an optical system () of the delivering device for low coherence optical radiation, in a particular embodiment, an optical fiber probe (), includes at least two lens components (), (), which have a positive focal power and are positioned substantionally confocally. This ensures a constant propagation time for the low coherence optical radiation propagating from a given point of the transverse scanning surface () or () to a corresponding conjugate point of the image plane (). That provides elimination of the transverse scanning related aberration of the optical path length for low coherence optical radiation directed towards the object () both for a flat transverse scanning surface () and for a transverse scanning surface () having a curvature. In another embodiment, together with the substantionally confocal arrangement of lens components (), (), the longitudinal scanning is performed by varying the optical path length for the low coherence optical radiation propagating from the transverse scanning surface () to the optical system (), i. e. , from the end face () of the distal part () of the optical fiber () to the optical system ().

Common Path Time Domain Optical Coherence Reflectometry/Tomography Device

View page
US Patent:
7538886, May 26, 2009
Filed:
Aug 22, 2006
Appl. No.:
11/466240
Inventors:
Felix I. Feldchtein - Cleveland OH, US
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G01B 9/02
US Classification:
356497
Abstract:
In common path time domain OCT/OCR devices optical radiation from a source is first split into two replicas, which are then delivered to an associated sample by an optical fiber probe. The tip of the optical fiber probe serves as a reference reflector and also serves as a combining element that produces a combination optical radiation by combining an optical radiation returning from the associated sample with a reference optical radiation reflected from the reference reflector. The topology of the devices eliminates the necessity of using Faraday mirrors, and also allows for registering a cross-polarized component of the optical radiation reflected or backscattered from the associated sample, as well as a parallel-polarized component.

Inventors:
Felix I. Feldchtein - Cleveland OH, US
Assignee:
Imalux Corporation - Cleveland OH
International Classification:
G01B 9/00
A61B 6/00
A61B 18/22
US Classification:
25022711, 600182, 600478
Abstract:
An optoelectronic probe system with all-optical coupling includes an optoelectronic measuring console coupled with an optoelectronic probe via an optical connector. A supplemental optical signal having an operative wavelength other than an operative wavelength of the regular optical part of the optoelectronic measuring console is communicated to the optoelectronic probe along with the output signal from the optoelectronic measuring console. The supplemental optical signal is then selected by a wavelength-division multiplexer, converted to an electrical signal and used for powering respective components of the optoelectronic probe. Auxiliary signals are also used for identification and storing calibration parameters of the optoelectronic probe, counting events, such as number of sessions used, time in use, and the like.
