Phase-Referenced Doppler Optical Coherence Tomography

View page
US Patent:
7006232, Feb 28, 2006
Filed:
Apr 7, 2003
Appl. No.:
10/408745
Inventors:
Andrew M. Rollins - Highland Heights OH, US
Joseph A. Izatt - Raleigh NC, US
Volker Westphal - Hannover, DE
Cameron J. Pedersen - Cleveland Heights OH, US
Siavash Yazdanfar - Durham NC, US
Assignee:
Case Western Reserve University - Cleveland OH
University of Hospitals of Cleveland - Cleveland OH
International Classification:
G01B 9/02
US Classification:
356479, 356497
Abstract:
A phase-referenced Doppler optical coherence tomography (OCT) system includes a low-coherence optical radiation source and a reference source co-propagated to a sample arm and a reference arm. The low-coherence and reference optical radiation reflected from the reference and arms is detected by a pair of detectors, yielding OCT and reference interferometric data output signals. The reference interferometric data output signal can be used to correct the OCT interferometric to yield velocity-indicating images that are free from defects due to sample motion and/or interferometer jitter.

US Patent:
7061622, Jun 13, 2006
Filed:
Aug 5, 2002
Appl. No.:
10/213326
Inventors:
Andrew M. Rollins - Highland Heights OH, US
Joseph A. Izatt - Raleigh NC, US
Volker Westphal - Hannover, DE
Siavash Yazdanfar - Durham NC, US
Assignee:
Case Western Reserve University - Cleveland OH
University Hospitals of Cleveland - Cleveland OH
International Classification:
G01B 9/02
US Classification:
356497
Abstract:
An optical coherence tomography (OCT) system including an interferometer provides illuminating light along a first optical path to a sample and an optical delay line and collects light from the sample along a second optical path remitted at several scattering angles to a detector. In one embodiment, illuminating light is directed along a number of incident light paths through a focusing lens to a sample. The light paths and focusing lens are related to the sample and to both the incident light source and the detector. In another embodiment, a focusing system directs light to a location in the sample. A transmission grating or acousto-optic modulator directs light from the sample at an angle representative of the wavelength of the incident light on the transmission grating or acousto-optic modulator.

Method For Optical Coherence Tomography Imaging With Molecular Contrast

View page
US Patent:
7075658, Jul 11, 2006
Filed:
Jan 26, 2004
Appl. No.:
10/765010
Inventors:
Joseph A. Izatt - Durham NC, US
Divakar K. Rao - Indore, IN
Changhuei Yang - Durham NC, US
Michael A. Choma - Durham NC, US
Siavash Yazdanfar - Cambridge MA, US
Andrew M. Rollins - Cleveland OH, US
Brian E. Applegate - Durham NC, US
Assignee:
Duke University - Durham NC
Case Western Reserve University - Cleveland OH
International Classification:
G01B 9/02
US Classification:
356479
Abstract:
Spatial information, such as concentration and displacement, about a specific molecular contrast agent, may be determined by stimulating a sample containing the agent, thereby altering an optical property of the agent. A plurality of optical coherence tomography (OCT) images may be acquired, at least some of which are acquired at different stimulus intensities. The acquired images are used to profile the molecular contrast agent concentration distribution of the sample.

Microscope With Dual Image Sensors For Rapid Autofocusing

View page
US Patent:
7576307, Aug 18, 2009
Filed:
Apr 30, 2007
Appl. No.:
11/741839
Inventors:
Siavash Yazdanfar - Niskayuna NY, US
Robert John Filkins - Niskayuna NY, US
Assignee:
General Electric Company - Niskayuna NY
International Classification:
G02B 27/16
G02B 27/40
US Classification:
2502013, 2502012, 348349, 348350
Abstract:
A digital optical microscope includes a primary image sensor that generates a primary image of a sample at a primary frame rate, an auxiliary image sensor that generates an auxiliary image of the sample at an auxiliary frame rate that is faster than the primary frame rate, and a controller that adjusts a focal distance between an objective lens and the sample along an optical axis in response to the auxiliary image, thereby autofocusing the primary image on the sample. The primary image sensor generates the primary image in response to the autofocusing.
