Spectral Filtering,ral transmittance of the absorbing materials, the spectral reflectance of the reflecting materials, the spectral properties of the surface-treated materials, the spectral transmittance of filters and the spectral response of the radiation detector.

厚脸皮

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.

注射器

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.

Industrial and Military Applications,sensitivity. The invisible radiation emitted by different objects, which cannot be directly perceived by the eye, is thus transformed into recognisable message that are conveyed to us by an optoelectronic detection system.

Line Scanners,vailability of infrared cameras. The first-generation equipment described in detail in the previous chapters constitutes sophisticated instrumentation that is better suited to the laboratory than to the industrial environment.

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
