Rotating shutter system for hostile laser source location technique

A hostile laser source location technique employs a television camera in conjunction with a rotating shutter to pinpoint the location of a hostile laser source without placing the pilot/operator at risk for eye damage. For an attack scenario the pilot/operator could then make changes in his tactics to negate the source or to continue his attack run. The shutter made of high optical density material (e.g., OD-4), except for an open aperture, provides optics protection for the camera system from both damage and dazzle. A detector is used to detect the laser pulse (flash) which immediately signals the proper frame to be frozen on a monitor. The laser source appears as a bright spot and is easily pinpointed.
