Several classes of laser detection, characterization, and warning receivers have been developed for employment on civilian and military aircraft. Traditionally, these sensors undergo extensive laboratory and ground characterization and testing, but very little validation and direct-illumination during actual flight. Moreover, the cost limits their use for small-scale development and test activities.
Air Force researchers have addressed this in a patent for a low-cost laser sensor stimulator to provide an agile means to support the development, testing, and periodic validation of ground and airborne laser sensors.
