Abstract
This paper describes a low cost, high performance, and hand- held staring Platinum Silicide (PtSi) medium wave infrared imaging system developed by Chung Shan Institute of Science and Technology. The infrared imaging system utilizes an monolithic 256 X 244 pixels PtSi staring focal plane array sensor, cooled by a stirling cryocooler. The sensor is integrated into a miniature dewar/cooler assemblies; this approach provides unsurpassed reliability and low power consumption at affordable cost. The camera system achieves an Noise Equivalent Temperature Difference of less than 0.1 degree(s)K at 300 degree(s)K background with f/1.4 optics at 30 Hz frames rate. At a spatial frequency of 1/2 Nyquist frequency the vertical and horizontal Minimum Resolvable Temperature Difference are in the range of 0.12 degree(s)K.
