ABSTRACT:
A technique for internal forward looking infrared (FLIR) system detection laser pulses. For scanning systems image pixel output of each frame is sampled as image data which is used to determine a pattern of saturated image pixels. The pattern of saturated image pixels is compared to predetermined laser pulse patterns and is then analyzed to determine if a laser pulse was detected. For staring systems, the patterns are compared to previous and following frames to determine if short lived large changes occur to determine if a laser pulse was detected.
