Lockheed Martin IR Imaging Systems is developing low cost, high performance, uncooled IR imaging products for both military and commercial applications. These products are based on microbolometer technology, a silicon micromachined sensor that combines wafer level silicon processing with a device structure capable of yielding excellent imaging performance. We report on several applications that are utilizing the Lockheed Martin microbolometer sensor. The performance of our basic uncooled sensor has been measured to determine sensor capabilities for insertion into both military and commercial products. Nonlinearity of the sensor over a scene temperature range of 95 degrees C is less than 0.5%. Our sensor typically have temporal NETDs of less than 70 mK as well as spatial NETDs of less than 50 mK, with an instantaneous dynamic range of 84 dB, and a total dynamic range of 120 dB. MRTD performance is less than 0.4 degrees C at spatial frequencies more than 20% beyond Nyquist. Spatial noise variation over time has been measured and found to meet both commercial and military requirements with excellent spatial noise over wide scene and ambient temperature ranges. Our sensor is now used for applications ranging from hand-held radiometric camera to driving aids; from long range surveillance cameras to miniature cameras; from rifle sights to helmet mounted camera. These applications will be discussed along with their unique system level performance parameters.
