Abstract
There have been many advances in thermal imaging systems and components in recent years such that an infrared capability is now readily available and accepted in a variety of military and civilian applications. Conventional thermal imagers such as the UK common module imager use a mechanical scanning system to sweep a small array of detectors across the thermal scene to generate a high definition TV compatible output. Although excellent imagery can be obtained from this type of system, there are some inherent disadvantages, amongst which are the need for a high speed line scan mechanism and the fundamental limit in thermal resolution due to the low stare efficiency of the system. With the advent of two dimensional focal plane array detectors, staring array imagers can now be designed and constructed in which the scanning mechanism is removed. Excellent thermal resolution can be obtained from such imagers due to the relatively long stare times. The recent progress in this technology will be discussed in this paper together with a description of the signal processing requirements of this type of imaging system.
