Embodiment Construction
[0082] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that the described examples are for the purpose of facilitating the understanding of the present invention and do not have any limiting effect thereon.
[0083] The physical diagram and system block diagram of the temperature-controlled adjustable mid-wave infrared polarized radiation source and its polarization degree measurement system provided in this embodiment are shown in FIG. 2 . It includes standard blackbody source (EOI CDS 100-04) module, variable temperature transmission bracket (P / N GS21525) module and medium wave cooled polarisation thermal imager (JADE MWIR) module. The detection principle is: unbiased radiation of surface blackbody source Partially polarized light (consisting of partially polarized radiation ...
