Abstract
Devices and methods of minimizing the temporal error between pixels or groups of pixels on a focal plane array involving, on a focal plane array comprising at least two pixels or groups of pixels, at least one counter or ramp, and at least one trigger: determining the timing error associated with a time stamp associated with the at least two pixels or groups of pixels; storing the timing error associated with the at least two pixels or groups of pixels and the pixel or pixel group location; and using the stored timing error and pixel or pixel group location to correct subsequent time stamps associated with the at least two pixels or groups of pixels, wherein the timing error corresponds to a systematic error between the trigger and the counter or ramp value due to the location of a pixel or group of pixels on the focal plane array.
