24 Apr 2013 New uncooled MWIR imaging detectors from New Infrared Technologies (NIT) feature monolithically integrated readout circuitry and a digital interface for control and data readout (i/o).
The new TACHYON FPAs, available via Pacer, allow image acquisition frame rates of 2 kHz for the new larger resolution 80x80 pixel format FPA, and 10 kHz for the 32x32 pixel version.
The FPA sensors are built directly on top of the Si-CMOS readout circuitry (ROIC), so 8 inch substrates can be used which greatly reduces cost per device. The spectral response is mainly centred in the MWIR with a peak response @ 3.7 microns; the material has an extended response down to 1 micron.
The Si-CMOS ROIC is based in an innovative Active Pixel Sensor design; each pixel includes dark current correction, signal amplification, ADC stage, and programmable gain/offset compensation. This results in very high acquisition speed as most of the processing is made at pixel level, and all pixels are read simultaneously (snapshot acquisition).
The new TACHYON FPAs represent a major breakthrough for both civilian and military infrared sensing systems. Industrial applications may move from single point detectors to imaging detectors, capturing much more information and now at a similar price level. Military applications include Active Protection Systems (APS), Passive Infrared Cueing Systems (PICS), final guidance, intelligent ammunition and countermeasures, with an orientation to low cost system development.
