Battlefield Laser Detection Sensor

To address the Air Force need for next-generation miniature battlefield laser detectors, Physical Optics Corporation (POC) proposes to develop a new Battlefield Laser Detection (BLaD) sensor based on a nano-structured two-dimensional array of multiplexed angle- and wavelength-selective holographic optical elements fabricated on a thin DuPont photopolymer film and laminated on top of a two-dimensional array of photodetectors, which is a commercial off-the-shelf part. Only one of the 7776 multiplexed holograms responds to the particular laser wavelength coming from particular direction by creating a unique interference pattern, and these interference patterns will be processed by the electronic signal processors and OEM onboard computer in real time. This device will cover all existing battlefield lasers in the range from UV to IR. The BLaD sensor has a wide FOV and high angular resolution in a lightweight module the size of a credit card. It detects the laser beam direction, wavelength, and power by electronic signal processing that overcomes the limitations of existing battlefield laser detection systems. In Phase I POC will demonstrate the feasibility of the BLaD sensor prototype. In Phase II POC plans to develop an engineering prototype of the laser sensor, and test it under appropriate operating conditions.
