Abstract
A LADOR circuit is in signal communication with a pixel array. The LADOR circuit is configured to generate an integrator reset voltage based on a resistance of the at least one heated bolometer pixel, and to detect laser energy incident on the at least one heated bolometer pixel based on a comparison between the integrator reset voltage and an input threshold voltage (Vthreshold).
