Original Abstract Submitted
An apparatus includes a pixelated photodiode array (PDA). Each pixel in the PDA includes a radiation detector, a memory configured to store a negative bias voltage for the PDA and a nominal breakdown voltage for each pixel in the PDA, and a read out integrated circuit (ROIC) communicatively coupled to the PDA and the memory. The ROIC is configured to read, from the memory, the negative bias voltage for the PDA and the nominal breakdown voltage for each pixel in the PDA, determine a difference between the negative bias voltage for the PDA and the nominal breakdown voltage for each pixel in the PDA, and adjust an arm/disarm bias voltage for each pixel in the PDA based on the difference between the negative bias voltage for the PDA and the nominal breakdown voltage for each pixel in the PDA.
