Broadband Pyro-Electric Infrared Area Detector, 2-14um

This broadband IR area detector has a sensor size of 320 x 240 pixels and a spectral range of 2-14 μm. The pixel size is 48.5μm square. The sensor is an uncooled pyroelectric BST (Barium, Strontium, Titanate) array. Because of the nature of pyroelectric sensors, there is an internal Archimedes spiral chopper that recalibrates the image. However, this calibration system, called an Auto Image Calibration, is actually a benefit for the user. The detector self calibrates to a reference 60 times per second, which in turn causes the system to be extremely stable and to have very little fixed pattern noise.
