Abstract:
A system and method for enhancing laser contrast on a remote target utilizing an image processor and a laser power controller is provided. An image processor in an imaging device manipulates a laser power controller in a laser system so that a laser beam emitted from a laser system is ultimately synchronized with the imaging device. Firstly, the original laser signal is shifted one time frame relative to the plurality of time frames to create a shifted laser signal. Secondly, the shifted laser signal is subtracted from the original laser signal. Thirdly, the subtracted laser signal is magnified by a frequency band pass filter. The filtered laser signal is added to the original signal to become the finalized laser signal which has better contrast than the original signal.
