| 20120013913 | FIBER-BASED INTERFEROMETRIC DEVICE FOR MEASURING AXIAL DIMENSIONS OF A HUMAN EYE - An apparatus for measuring a layered object comprising a low coherence light source, a coherent light source, and an interferometer including a reference arm and a measurement arm. The reference arm is comprised of a first section of polarization maintaining optical fiber engaged with a first fiber stretcher. The measurement arm is comprised of a second section of polarization maintaining optical fiber engaged with a second fiber stretcher. The first and second fiber stretchers are driven so as to alternatingly vary the lengths of the first section of polarization maintaining optical fiber and the second section of polarization maintaining optical fiber, thereby causing interference signals with the low coherence light when the length of the reference arm is equal to the length of the measurement arm including the distance from the second section of polarization maintaining optical fiber to any of the surfaces of the layers of the object. | 01-19-2012 |
| 20110128552 | ROTATIONAL AND LINEAR SYSTEM AND METHODS FOR SCANNING OF OBJECTS - A scanning system comprised of a multi-axis drive module comprised of a first linear drive operable along a first axis, a second linear drive joined to the first linear drive and operable along a second axis non-parallel to the first axis, and a first rotary drive mounted on the second linear drive, operable around an axis parallel to the first axis, and comprised of a rotary fixture for holding the object. A first optical probe is provided for scanning the object. The rotary fixture for holding the object may include a central object-receiving port. A first fluid circuit may be provided, which is in communication with the central object-receiving port. In that manner, an internal cavity of the object may be pressurized through a passageway in the portion of the object that is disposed in the central object-receiving port, thereby stabilizing a region of the object to be scanned. | 06-02-2011 |
| 20110090461 | APPARATUS FOR MEASUREMENT OF THE AXIAL LENGTH OF AN EYE - An apparatus for measuring the axial length of a human eye, the apparatus comprising a low coherence light source; a beam splitter; a fast displacement module for rapidly varying the path length within a reference arm of an interferometer; a laser directing a laser beam that is co-propagating with light from the low coherence light source into the displacement module. | 04-21-2011 |
