Abstract
A system, method, and device for simulating an IR signature to test an IR detection device. At least one infrared LED display is provided. Each infrared LED display contains infrared LEDs that emit the desired IR signature. A reflector reflects the IR signature toward the IR detection device. The configuration of the reflector is dependent upon the configuration of the infrared LED display and whether or not some intermediate lens system is used. The IR signature is collimated as it travels to the IR detection device. The IR signature can be collimated by the reflector or by an added lens system. The IR signature fills the field of view associated with the IR detection system. The IR signature comes from a computer-controlled display. As such, the system can simulate various IR signatures and move those IR signatures throughout the field of view of the IR detection system.
