Abstract

The detector is the heart of an imaging system because it converts infrared radiation into a measurable electrical signal and converts target spatial information into electrical temporal information. Amplification and signal processing create an electronic image in which voltage differences represent scene intensity differences. The detector electronics are matched to the detector characteristics and required output. Many systems digitize signals because of the relative ease of creating an image. In addition, many digital image enhancement algorithms are available. Machine vision systems typically operate in the digital domain.
