General Description
The AIRIS-Wide Detector is a passive multispectral imaging system designed specifically to address the need to detect chemical agent and toxic industrial chemical releases from fixed site, ground mobile, and airborne platforms. The system incorporates advanced infrared focal plane array technology to enable high spatial resolution for the detection of smaller releases while affording the rapid data acquisition capability needed to operate from moving platforms without degradation of sensitivity. The system’s real-time processor provides immediate identification, display, and geo-location of threats using integrated GPS and pointing systems. On board capability is present to transmit threat location via the Joint Warning and Reporting Network.
Technical Description
The system consists of a Fabry-Perot interferometer with 10 wavenumber spectral resolution and 8 to 11 micron tuning range. It incorporates an advanced low-noise 256 x 256 pixel HgCdTe focal plane array with integrated cooled optics and a FPGA/DSP based real-time signal processor incorporating multi-frame signal averaging for sensitivity enhancement. A MIL-STD-810E qualified operator display unit with simplified button-initiated pull-down window control is also included. Remote display and RS-232 based control is possible including air to ground telemetry.
