Abstract

InfraredVision Technology Corporation ("ITC") has improved the performance of the 320x240 microbolometer Uncooled Focal Plane Array ("UFPA") by increasing the pixel fill-factor. This allows state-of-the-art performance for applications requiring high sensitivity. Measurements taken on microbolometer test structures and detector arrays show a factor of two improvements in the responsivity over that previously reported for our standard 37.5-um pixel UFPA. Performance results for microbolometer pixels ranging in size from 50um down to 15um are presented. Our ITC-1000 series detector product addresses both imaging and radiometric commercial-camera applications. With the development of a high fill-factor pixel design, ITC will soon provide a high-performance VOx microbolometer-based sensor to camera manufacturers requiring state-of-the-art detector performance. FPA performance is presented to demonstrate the sensor improvements accomplished. The use of our on-chip NonUniformity Correction (NUC) feature, available on the ITC-1000 detector, is characterized to demonstrate the performance limitations.
