Title The design of Infrared radiation light source
Abstract
The infrared radiation source is composed of a variety of infrared instruments, the
far-infrared heating and infrared interference. Its performance has a direct impact on
the quality of the infrared instruments and far-infrared heating. In this paper, point
blackbody achieved good results in practical applications. This paper has a discuss on
parameter calculation of blackbody radiation source and observing the actual
simulation results. The main task of this paper is to discuss the performance of the
infrared radiation source, the selection of parameters, the infrared radiation
characteristics and effective range of point or surface radiation sources, the principle of
the structure of the typical blackbody source, radiant emittance, and the calculation of
the radiated power. Finally, on the basis of source of infrared radiation the optical
system is designed. And it gives the calculation method of beam scattered angle, small
aperture area and the use of off-axis parabolic reflecting mirror.
