Abstract

Infrared analysis is re-examined in the light of the current status of imaging infrared technology. The spectral, spatial and temporal characteristics are all considered from the outset, the analysis being structured such that the sub-system characteristics associated with the infrared scene, transmission, detection and optoelectronic spread processes are separated, wherever possible. Each sub-system may therefore be examined on an essentially independent basis. The radiometric, temporal and spatial contributions are all readily apparent within the separated formulae that are derived for the signal, noise and SNR.
