1. A focal plane imaging apparatus comprising: a plurality of photodetectors, the plurality of photodetectors comprising a first photodetector to convert a first portion of light that is scattered and/or reflected from a scene into a first analog signal and a second photodetector to convert a second portion of light that is scattered and/or reflected from the scene into a second analog signal; a plurality of analog to digital converters (ADCs), the plurality of ADCs comprising a first ADC electrically coupled to the first photodetector and configured to convert the first analog signal into a first digital signal and a second ADC electrically coupled to the second photodetector and configured to convert the second analog signal into a second digital signal; a plurality of digital registers, the plurality of digital registers comprising a first digital register electrically coupled to the first ADC and configured to store a first digital number representing the first digital signal and a second digital register electrically coupled to the second ADC and configured to store a second digital number representing the second digital signal; and a distributed control pattern generator operably coupled to the plurality of ADCs and/or the plurality of digital registers and configured to modulate, at a rate faster than a readout rate of the plurality of digital registers, storage of the first digital number with a first pseudo-random modulation and to modulate storage of the second digital number with a second pseudo-random modulation so as to control spatial correlation of the first digital number with the second digital number.
