TERMINAL-IMAGING SEEKER USING A SPATIAL LIGHT MODULATOR BASED CODED-APERTURE MASK

摘要

Apparatus and associated methods relate to creating corrected images of a scene for a terminal-imaging seeker using an electrically-controllable coded-aperture mask pattern embodied in a programmable spatial light modulator (32). The coded-aperture mask pattern includes a plurality of pinhole-like apertures (34), each of which is configured to perform pinhole-like lensing of the scene. The plurality of pinhole-like apertures form a multiplex of overlapping images on a focal plane array aligned with the optical axis. An image processor (64) reconstructs, based on a configuration of the plurality of pinhole-like apertures and the multiplex of overlapping images, a single image of the scene.
