Profile: Physical Optics Corp. specializes in providing optoelectronic solutions and products. OptiKey® is a unique optical signature recognition system for authenticity verification. With the OptiKey® system labels, identification cards, and documents are impossible to counterfeit, copy, or duplicate. This system consists of a mass producible optical mask (ID Label) and a matched optical reference mask located in the optoelectronic reader / correlator. The optical ID label is a randomly recorded optical surface structure, which is placed on labels / cards and documents. For secure validation, the optical surface structure of the ID label must match the optical reference mask in the correlator. The optical match is achieved with a joint fourier transform which also ensures quick and easy alignment. We provide optical proximity sensor (OPS™) for small caliber non-lethal munitions and proximity detection. The miniature optical sensor generates an electric output signal if a light reflecting target emerges at a predefined distance in front of the sensor. The angle of viewis 2 milliradians by 7.8 milliradians (0.11 degree X 0.44 degree). OPS™ can be installed on a shooting projectile as small as 12-gauge caliber (OD: 17.8mm -12 gauge and 19mm in length which includes PC board).
