Title:
SYSTEMS AND METHODS FOR BREAKDOWN VOLTAGE CORRECTION IN GEIGER-MODE AVALANCHE PHOTODIODE (APD) FOCAL PLANE ARRAYS (FPA)
Document Type and Number:
WIPO Patent Application WO/2023/234755
Kind Code:
A1
Abstract:
Systems and methods are described for optical processing. According to some aspects an apparatus may include a pixelated photodiode array (PDA), wherein each pixel in the PDA includes a radiation detector. The optical processing apparatus may also include a memory that stores one or more characteristics for each pixel in the PDA, and a read out integrated circuit (ROIC) communicatively coupled to the FPA and the memory. In some aspects, the ROIC reads from the memory the one or more characteristics for each pixel in the PDA, and adjusts an arm/disarm bias voltage for each pixel in the PDA based on the one or more characteristics of each pixel.
