Image De-Blurring Algorithm in Rotational Platform Using Fast Steering Mirror

Image captured from cameras can get blurred when it is mounted on rotating platform like gimbal, which is moving continuously at high speed and high acceleration. Scanning and surveillance application requires panoramic image or video to be generated from continuously rotating platform. The method employed here uses two motorized mirrors along optical axis, one for scanning the view mounted on a gimbal and another mounted on Fast steering mechanism for freezing the scene during the exposure time of the camera detector. The motion of gimbal and angular velocity of fast steering mechanism are synced in position and time with frame acquisition in camera to obtain a de-blurred image. Fast steering mirror (FSM) is used to compensate blurred image caused by scan motion of platform.
