Title:
SYSTEMS AND METHODS FOR PIXEL ON-OFF SWITCHING IN FOCAL PLANE ARRAYS
Document Type and Number:
WIPO Patent Application WO/2023/239127
Kind Code:
A1
Abstract:
Systems and methods are described for optical processing. According to some aspects an optical processing apparatus may include a pixelated photodiode array (PDA), each pixel in the PDA includes a radiation detector. The apparatus also includes a read out integrated circuit (ROIC) that includes a logic circuit and a plurality of switch elements. The plurality of switch elements being switchable between an armed state for arming its corresponding radiation detector and transmitting a signal received from the corresponding detector to the ROIC, and a disarmed state for disarming its corresponding detector and blocking transmittal of the signal, wherein in the armed state, the PDA is configured to detect an incoming optical signal and in the disarmed state, the PDA is configured to disregard the incoming optical signal. Moreover, the logic circuit controls a switch state of a selectable switch element associated with a radiation detector.
