International Classification

G01J 5/08

U.S. Classification

250340, 250349

Abstract

A multiple field-of-view telescope and optical sensor system and imaging methods using the system. In one example, an optical sensor system includes a primary imaging detector having a first field of view, a telescope configured to receive and focus electromagnetic radiation onto the primary imaging detector along a primary optical axis, a secondary detector having a second field of view different from the first field of view, and relay optics configured to direct and focus a portion of the electromagnetic radiation onto the secondary detector. In certain examples, the system further includes a fold mirror positioned to reflect the portion of the electromagnetic radiation to the relay optics.

International Classification

G02B 27/01, G02B 3/02, G06F 3/01

Abstract

An optical assembly for an eye-tracking camera includes an aperture stop, a first optical surface, and a second optical surface. The optical assembly is configured to receive non-visible light reflected or scattered by an eye and to direct the non-visible light to an image sensor along an optical path, where the non-visible light is received from an optical combiner of an eye-tracking system. The first optical surface is disposed on the optical path and is configured to correct for field-independent optical aberrations induced by the optical combiner. The second optical surface is disposed on the optical path and is configured to correct for field-dependent optical aberrations induced by the optical combiner.

International Classification

H01J 3/14, G01J 1/04

U.S. Classification

250216, 250237 R

Abstract

Asymmetric rotating stray light baffles are provided for conformal dome two-axis seekers having arch corrector optics mounted on the outer gimbal. A pair of side skirt baffles are mounted on opposite sides of the arch corrector optics on the outer gimbal extending forward beyond the transparent arch adjacent but not touching the inner surface of the dome and extending aft beyond the forward most receiver optic for all fields of regard (FOR). The optical system may also include: (a) an annular objective baffle mounted on and around the receiver optics on the inner gimbal and between the pair of side skirt baffles, the objective baffle extending forward of the receiver optics without interfering with the receiver optics' FOV and without interfering with the transparent arch as the inner gimbal rotates, (b) a plurality of fin baffles mounted between the side skirt baffles on the outer gimbal that extend forward adjacent but not touching the inner surface of the dome and aft of the transparent arch, each fin baffle positioned to reduce the cross-section seen by the receiver optic when rotated in the direction of that fin baffle and (c) central baffles (short or long) along the axis of symmetry that obscure a portion of the receiver optics' FOV at a zero degree angle of rotation about the second axis.

International Classification

G02B 26/10, G02B 26/08, G02B 27/28, G02B 27/01

Abstract

A scanning projector display includes a plurality of light engines coupled to a MEMS scanner. Each light engine includes a light source subassembly for providing a diverging light beam optically coupled to a collimator for collimating the diverging light beam. In operation, the collimated light beams of the plurality of light engines impinge onto the tiltable reflector at different angles of incidence. A controller may be operably coupled to the light source subassembly of each light engine of the plurality of light engines and the MEMS scanner for tilting the tiltable reflector of the MEMS scanner. The controller is configured to energize the light source of each light engine in coordination with tilting the tiltable reflector for displaying the image.
