| Abstract: | Based on finite element thermal analysis method,the difform blackbody cavity sensor model was established,and the blackbody cavity emissivity was calculated.The factors that influenced the cavity emissivity,such as the aperture,the axis length of cavity,the distance between the aperture and the detector,the radius of detector surface and the material emissivity were analyzed.The optimal high temperature blackbody cavity sensor was designed by comparing the emissivity of blackbody cavity of different shapes.... |
