Radiation Detectors,covery of the ultraviolet by Ritter in 1801 (effect on photosensitive materials), there has been a need for the quantitative detection of radiation in the spectral region visible to eye. Indeed, it is often advantageous to be able to work outside the visible region because of the low sensitivity of visual photometric methods.

Imaging and Measurement, field is the source of the instantaneous power received within the solid angle of the infrared detector. In addition, the spatial resolution of the system depends on other factors such as the quality of the optics, the speed of spatial analysis, which involves the electrical pass band, and the various filters used in signal processing.

Optical Image Formation,t converts it into an image which is subsequently analysed in terms of a spatial discrimination model. The radiation detection capability of the system is limited by the properties of its optical components. These limitations arise, on the one hand, from geometrical and chromatic aberrations and on
