Abstract
In accordance with at least one aspect of this disclosure, a lens is provided. The lens can be used in an imaging platform of a moving platform (e.g., a projectile or guided munition), for example, in a seeker arrangement. The lens can be configured to optical rotation information of the moving platform to an optical sensor as the moving platform moves in space, for example, following a mission profile.
Claims20
A system, comprising:
- a lens;
- an optical sensor configured to receive image data through the lens;
- one or more mirrors optically connected to the lens to reflect inertial information to the optical sensor;
- and
- a controller operatively connected to the optical sensor, the controller configured to determine at least one of direction, pitch, roll, and/or yaw of a moving platform based at least in part on the inertial information received by the optical sensor;
- wherein the optical sensor defines at least a first pixel area and a second pixel area, wherein the first pixel area includes seeker pixels configured for tracking a target and the second pixel area includes inertial pixels configured for aiding tracking the target.
3 more elements
A lens assembly, comprising:
- a lens defining a primary optical axis, having an inner surface and an outer surface;
- one or more reflective surfaces optically connected to an outer perimeter of the lens oriented orthogonal to the primary optical axis, configured to reflect optical rotation information to an optical sensor while allowing electromagnetic radiation to pass to the lens through an aperture radially inward of the outer perimeter;
- and
- a mask optically connected to one or more of the lens or the one or more reflective surfaces, the mask defining a masked portion and a transparent portion of the lens, wherein the masked portion substantially aligns with the one or more reflective surfaces such that electromagnetic radiation originating from the outer surface of the lens passes directly through the transparent portion of the lens to a first portion of the optical sensor only, and electromagnetic radiation originating from the outer perimeter and/or the inner surface of the lens is reflected to a second portion of the optical sensor only.

A system, comprising:
- a lens;
- an optical sensor configured to receive image data through the lens;
- one or more mirrors optically connected to the lens to reflect inertial information to the optical sensor;
- and
- a controller operatively connected to the optical sensor, the controller configured to determine at least one of direction, pitch, roll, and/or yaw of a moving platform based at least in part on the inertial information received by the optical sensor;
- wherein the controller is configured to control one or more control surfaces of the moving platform to adjust a flight path of the moving platform based at least in part on the inertial information received by the optical sensor to account for the at least one of direction, pitch, roll, and/or yaw of the moving platform.
