Abstract:
An optical apparatus (fig. 1) for producing light of a predetermined intensity from light sources of less than the predetermined intensity includes a first light source; a second light source; a double dove anti-Gaussian generator in optical communication with the first light source; and a compensator in optical communication with the second light source. Light from the first light source passes through the double dove anti-Gaussian generator and light from the second light source passes through the compensator, and are combined to produce a flattened Gaussian intensity distribution.
Abstract:
A method and apparatus are directed to characterizing a continuously moving pharmaceutical manufacture via interferometry-based scanning. The method includes forming a depth characterization of the pharmaceutical manufacture along a scan line on the surface of the pharmaceutical manufacture. During the scanning, the pharmaceutical manufacture undergoes continuous motion. The method further includes combining the determined depth characterization along the scan lines of the plurality of scan lines to form a depth map representing at least a depth of a portion associated with a location on the surface of the pharmaceutical manufacture in the third direction on a grid of locations arranged in the first and second directions. Forming the depth characterizations includes scanning a frequency dispersed pulsed optical signal in a first direction across the continuously moving pharmaceutical manufacture, the pharmaceutical manufacture moving in a second direction substantially orthogonal to the first direction. The scanned optical signal forms a scan line on a surface of the pharmaceutical manufacture in a third direction substantially orthogonal to the first direction and the second direction.
Abstract:
In one aspect, the invention relates to an optical apparatus for producing light of a predetermined intensity from light sources of less than the predetermined intensity. In one embodiment the apparatus includes a first light source; a second light source; a double dove anti-Gaussian generator in optical communication with the first light source; and a compensator in optical communication with the second light source. Light from the first light source passes through the double dove anti-Gaussian generator and light from the second light source passes through the compensator, and are combined to produce a flattened Gaussian intensity distribution. In another aspect, the invention relates to a method and apparatus for separating an image into subunits and reading the separate subimages out of the detectors in parallel.
Abstract:
This invention is directed towards ophthalmic lenses used to assist during vitreoretinal surgery. More specifically, it is directed towards Ophthalmic lenses that are constructed to generate a high-resolution image of the retinal surface during surgery while maintaining a minimal mechanical envelop all while using materials and assembly methods compatible with autoclave sterilization techniques.
Abstract:
A method of increasing the spatial uniformity of the detected intensity of a beam of light from a laser in a system including the laser (34) and a light detector (74). In one embodiment the method includes the steps of generating a beam of light (30) with the laser; and moving the beam of light and the light detector relative to each other, such that the detector averages the spatial intensity of the beam of light over time. In another embodiment the invention relates to a system for increasing the detected spatial uniformity of the intensity of a beam of light. In one embodiment the system comprises a light detector; a laser source for generating the beam of light; and a means (10) for moving the beam of light and the detector relative to one another such that the detector averages the intensity of the light beam over time.

Abstract:
A compliant gear assembly (20, 120, 220, 420) includes a gear ring (22, 122, 222, 422) positioned about a hub (26, 129) and configured to translate responsive to a torque on the gear assembly (20, 120, 220, 420), and biased toward co-axial alignment with the hub (26, 129) via at least one actuator (31, 52, 152, 252, 452). A method of managing loads on an idler gear (20, 120, 220, 420) in the gear train (11, 41 1) is still further provided including translating the gear ring (22, 122, 222, 422) responsive to the torque on the idler gear (20, 120, 220, 420). A work machine (8) includes an engine (10, 410) having a housing (12, 412) and a geartrain (11, 411) mounted thereon, the geartrain (11, 411) including a crank gear (14, 418), a cam gear (19, 419) and a compliant idler gear assembly (20, 120, 220, 420).
