High dynamic range micromirror imaging array systems and methods

Abstract

A system comprises a digital micromirror device (DMD), an image sensor comprising an array of sensors operable to capture an image of a scene, a readout integrated circuit (ROIC) operable to generate signals from the sensors corresponding to the captured image of the scene, and an image reconstruction module. The image sensor is operable to capture an image of a scene and comprises an array of photodetector sensors operable to capture an image of a scene at a first frame rate, and a read a readout integrated circuit (ROIC) operable to generate signals from the photodetector sensors corresponding to the captured image of the scene at a second frame rate. A digital micromirror device (DMD) comprising a plurality of micromirrors, each micromirror having at least two physical states, and control circuitry operable to separately control the state of each micromirror, the digital micromirror device operable to receive the image of a scene and reflect the image to the image sensor, whereby the image sensor captures the reflected image of the scene. A processing component is operable to control the operation of the DMD and reconstruct the image from the ROIC.
