Uncooled focal plane array detector development at InfraredVision technology corporation

InfraredVision Technology Corporation ("ITC") has developed a low-cost Uncooled Focal Plane Array ("UFPA") for commercial applications. The ITC-1000 series detector module has been targeted for both imaging and radiometric camera applications. The 320x240 VOx microbolometer-based sensor exploits a 37.5-mum pixel structure to provide potential cost reduction for the camera manufacturers. The CMOS Readout Integrated Circuit ("ROIC") design offers on-chip nortuniformity correction capability and gain control. As an additional feature, the design allows non-temperature stabilized operation. The integration time can be varied for applications where large variations in infrared radiation must be accommodated. Vacuum packaging of the sensors is accomplished using low-cost metal design. A radiometric version of this detector, the ITC-1100, has also been developed for thermographic applications.
