Compact laser detection system based on Multi-spectral Mosaic (MSM) filter arrays and DMD AoA determination

Compact, low-cost laser warning systems are in high demand for military and other commercial avionics platforms. This looming threat has recently gained national attention with reports of laser cockpit breaches in commercial aircraft over the past few months. Present laser warning systems (LWS) are somewhat bulky when all features are integrated as a complete laser profiling analysis system. Expansion of the Color Filter Array (CFA) beyond standard RGB or CMY sets to a mosaic pattern that included filters which could discriminate and classify all known laser threats in a single image acquisition step would be ideal. Because silicon CMOS technology is operational through the visible and near-IR (up to ~ 1050 nm), the CFA can be expanded to a mosaic pattern that would provide real-time laser threat analysis. To this end, Nanohmics proposes to develop a process for multiplex deposition of Multi-Spectral Mosaic (MSM) Filter Arrays directly on the CMOS sensor surface (e.g. narrow bandpass color and near-IR filters).
