Digital ROIC enhancement and repetition frequency decoding of asychronous laser pulses

摘要

A method includes acquiring a pulse detection bitmap from an imaging sensor array into a digital read out integrated circuit (DROIC), filtering the pulse detection bitmap within the DROIC to convert the pulse detection bitmap into a filtered pulse detection bitmap, and determining for a given pixel in the filtered pulse detection bitmap whether the pixel has a value that exceeds a threshold, indicating a true laser pulse return has been detected in the pixel.
