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.

Laser spot contrast enhancement

Embodiments of the invention are directed to methods and apparatus for infrared imagers including fast electrostatic shutters and offset compensation. Fast electrostatic shutters are used for video image correction including image offset compensation where temporal noise and scene nonuniformity are corrected. This method provides a shutterless experience for the user because the image will be blocked for only one frame at a time. A method of manufacturing an electrostatic infrared shutter includes a conductive infrared-transparent substrate, covering it with an insulating layer, depositing adhesive and a thin film stack, delineating a working area, providing contacts, heat-treating the assembly, and making the polymer non-reflective in the infrared.
