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-mu m pixel UFPA. Performance results for microbolometer pixels ranging in size
from 50 mu m down to 15 mu m 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.
