| Application No. | Application Title | Issue Date |
| 20080186507 | HIGHLIGHTING GAPS IN A SURFACE A surface gap detector facilitates determining conformance of a surface of an object by providing a light source integrated into the detector that diffusely illuminates the surface of the object so that a user may observe the light that passes between the detector and t... | 08/07/2008 |
| 20070064241 | Tracking algorithm for linear array signal processor for fabry-perot cross-correlation pattern and method of using same An algorithm and method for calculating an interferometric gap is disclosed that comprises providing an interferometric sensor having a first gap and an interferometric correlation element having a second gap placed in series with the first gap. A correlation burst wave... | 03/22/2007 |
| 20060274323 | High intensity fabry-perot sensor In a Fabry-Perot interferometer based sensor if insufficient light reflected from the sensor re-enters the fiber, the results from the Fabry-Perot interferometer-based sensor are compromised. Accordingly, a sensor assembly is provided that comprises an optical fiber hav... | 12/07/2006 |
| 20060192976 | Highly-sensitive displacement-measuring optical device Micron-scale displacement measurement devices having enhanced performance characteristics are disclosed. One embodiment of a micron-scale displacement measurement device includes a phase-sensitive reflective diffraction grating for reflecting a first portion of an incid... | 08/31/2006 |
| 20060181712 | Highly-sensitive displacement-measuring optical device Micron-scale displacement measurement devices having enhanced performance characteristics are disclosed. One embodiment of a micron-scale displacement measurement device includes a phase-sensitive reflective diffraction grating for reflecting a first portion of an incid... | 08/17/2006 |
| 20060017934 | Interferometer calibration methods and apparatus A method for calibrating an interferometer uses an actuator adapted to control an optical gap in response to application of an electrical signal. The interferometer is illuminated with a beam of light having a predetermined substantially monochromatic wavelength, orient... | 01/26/2006 |
