Abstract
Infrared focal plane array (IRFPA) is a bi-dimensional array of micro scaled infrared detectors which become essential sensing devices in a wide range of applications. Due to the need for mobility and power saving, new uncooled IRFPA’s have become more suitable to substitute cooled IRFPA in many applications that require lighter weight and lower power consumption. Electronic Designers aim to reduce power consumption by integrating circuits inside high-density chips, invent new solid state components which consume less power and eliminate excess components when they are rare to use. This paper focuses on eliminating high speed digital data link channel from low profile portable IR camera and instead of that, it proposes manipulating bit arrangements by video processing unit to overcome video signal major issues like noise, clipping, and pixel resolution.
Keywords: IRFPA, uncooled thermal camera, calibration, TPC, FPGA, Verilog, LabVIEW, composite video, DAC, GigE, white level clipping, low power consumption.
