Methods Of Imaging In Probe Microscopy

View page
US Patent:
7441447, Oct 28, 2008
Filed:
Oct 10, 2006
Appl. No.:
11/548005
Inventors:
Fahrettin L. Degertekin - Decatur GA, US
Abidin G. Onaran - Atlanta GA, US
Mujdat Balantekin - Atlanta GA, US
Assignee:
Georgia Tech Research Corporation - Atlanta GA
International Classification:
G01B 5/28
US Classification:
73105
Abstract:
In accordance with an embodiment of the invention, there is a force sensor for a probe based instrument. The force sensor can comprise a detection surface and a flexible mechanical structure disposed a first distance above the detection surface so as to form a gap between the flexible mechanical structure and the detection surface, wherein the flexible mechanical structure is configured to deflect upon exposure to an external force, thereby changing the first distance.

US Patent:
8391517, Mar 5, 2013
Filed:
Feb 10, 2011
Appl. No.:
13/025054
Inventors:
Brad D. Avenson - Pflugerville TX, US
Caesar T. Garcia - Austin TX, US
Neal Allen Hall - Austin TX, US
Abidin Guclu Onaran - Austin TX, US
Assignee:
Silicon Audio, Inc. - Austin TX
International Classification:
H04R 25/00
US Classification:
381172, 381369
Abstract:
An optical microphone that may include a first substrate with one or more acoustic entry ports and a die over the one or more acoustic entry ports. The die may include a sensing structure for detecting acoustic vibrations received via the acoustic entry port(s) and may form a first cavity between the first substrate and the sensing structure. The microphone may include a light source within the first cavity, which may transmit laser light. The optical microphone may include photo detector(s) within the first cavity. The one or more photodetectors may be configured to receive the laser light after reflection from the sensing diaphragm to measure the acoustic vibrations of the sensing diaphragm. The microphone may also include a circuit and a lid, where the die, light source, photo detectors, and circuit are comprised within the cavity of the microphone. The circuit may perform signal processing signals from the photodetector(s).

US Patent:
8488973, Jul 16, 2013
Filed:
Feb 10, 2011
Appl. No.:
13/025066
Inventors:
Brad D. Avenson - Pflugerville TX, US
Caesar T. Garcia - Austin TX, US
Neal Allen Hall - Austin TX, US
Abidin Guclu Onaran - Austin TX, US
Assignee:
Silicon Audio, Inc. - Austin TX
International Classification:
H04B 10/02
H04B 10/12
US Classification:
398133, 398132, 398134
Abstract:
Method for performing signal processing for an optical microphone. First and second signals corresponding to at least two beams may be generated or received. The first and second signals may be complementary, and may be based on signals provided by one or more photo detectors that receive the at least two beams after the beams return from a sensing structure. The first signal and the second signal may be subtracted to produce a third signal. A position of the sensing structure may be adjusted to cause the third signal to reach a first value, where the adjusting may be performed based on the third signal, and an audio output signal may be provided based on the third signal.

Method And Apparatus For The Ultrasonic Actuation Of The Cantilever Of A Probe-Based Instrument

View page
US Patent:
20030041669, Mar 6, 2003
Filed:
Mar 12, 2002
Appl. No.:
10/096367
Inventors:
F. Degertekin - Decatur GA, US
Abidin Onaran - Atlanta GA, US
Babur Hadimioglu - Stockholm, SE
International Classification:
G01B005/28
G01D021/00
US Classification:
073/651000, 073/105000
Abstract:
The cantilever of a probe-based metrology instrument such as an AFM is deflected by directing a beam of ultrasonic energy at the cantilever to apply ultrasonically generated acoustic radiation pressure to the cantilever. The energy is generated by an ultrasonic actuator such as a ZnO transducer driven by a power source such an RF signal generator. The transmitted beam preferably is shaped by focusing, collimation, or the like so that it impinges at least primarily on a region of interest of the cantilever such as the free end. The ultrasonic actuator produces a much better controlled force on the cantilever than can be achieved through the use of a traditional piezoelectric actuator and, accordingly, produces a response free of spurious effects (at least when the cantilever is operating in liquid). It also has a frequency bandwidth in the MHz range.

US Patent:
20160295333, Oct 6, 2016
Filed:
Jun 14, 2016
Appl. No.:
15/182233
Inventors:
- Austin TX, US
Caesar T. Garcia - Austin TX, US
Bradley D. Avenson - Austin TX, US
Abidin Guclu Onaran - Austin TX, US
International Classification:
H04R 17/02
H04R 1/34
Abstract:
In some embodiments, a microphone system may include a deformable element that may be made of a material that is subject to deformation in response to external phenomenon. Sensing ports may be in contact with a respective region of the deformable element and may be configured to sense a deformation of a region of the deformable element and generate a signal in response thereto. The plurality of signals may be useable to determine spatial dependencies of the external phenomenon. The external phenomenon may be pressure and the signals may be useable to determine spatial dependencies of the pressure.
