Multi-aperture optical system for high-resolution imaging

DWPI Title: Imaging system of imagery for use in connection with security surveillance application, has focal plane array (FPA) configured to output data indicative of intensity of light received at FPA
Abstract: Technologies pertaining to a multi-aperture optical imaging system are described herein. The multi-aperture optical system comprises an afocal optical telescope and a plurality of sub-apertures that receive light from the telescope. Each sub-aperture comprises a focusing optic that creates a full-field image onto an individual image sensor that outputs data indicative of an intensity of light received at the sensor. Image processing techniques can be used to combine the sensor outputs for spectral discrimination, to improve dynamic range or to enhance resolution of a scene.
Use: Imaging system of imagery for use in connection with many mapping, earth-monitoring, and security surveillance application.
Advantage: The reconstruction quality of phase diversity image generated by the imaging component is increased by increasing multiple FPAs and corresponding lens in contrast with phase diversity imaging system, a reconstruction quality of phase diversity image generated by the system is improved without for z-scanning. The reconstruction quality of a phase diversity image generally improves as multiple sample planes increases. The imaging component generates a phase diversity image that has an improved resolution as compared to an image generated based upon output of a single one of the FPAs.
Novelty: The system has an array of lenses (520) located at an exit pupil of a telescope (502). Each FPA (524) is configured to receive light from a respective lens in an array of lenses. Each lens in the array of lenses is configured to focus an image of a same field of view (FOV) at a respective FPA in the FPA. Each FPA is configured to output data indicative of an intensity of light received at the FPA. A computing system is configured to output a multispectral image data based upon outputs of the FPAs.
