Multi-Band / Multi-Threat Warning System with a Single Sensor

Agiltron and University of Oklahoma jointly propose a revolutionary multi-band/multi-threat warning system having intrinsic advantages in sensitivity, speed, energy efficiency, reliability, and cost as compared with the competitive approaches. The device integrates three-band detection and identification within a single sensor, eliminating the need of pixel registration and data fusion from multiple sensors while providing fast operation speed capable of over one hundred frames per second for each of the three bands. Equipped with Agiltron's proprietary 360-degree FOV fisheye lens and a 512x512 MEMS IR sensor array, the system can provide better than 1-degree over a field of view of 360-degrees in azimuth and in elevation (-10-degrees to +60-degrees). Moreover, the design is simple, compact, lightweight, low power consumption, rugged, and long operating life. The innovation is based on pixel-level integration of micro-machined thermal-mechanical and optical-reflective structures of bi-materials that directly convert an IR image into a visible image. The design incorporates direct optical readout, which eliminates the drawback of electronic means that inevitably introduces chip complexity and additional signal loss due to thermal contact made to the detector element.
