【摘要】：針對紅外輻射源輻射控制問題,設計了一種均勻可調紅外輻射源方案。分析了拋物柱面鏡的光學特性,給出了拋物柱面鏡反射后的輻射模型,并仿真模擬了拋物柱面鏡的準直效果,證明了拋物柱面鏡具有很好的會聚作用;對比了百葉窗和雙向推拉窗的輻射調節(jié)效果,推導了雙向推拉窗透光面積的變化模型,得到了推拉窗開口寬度與輻射功率之間的線性關系;基于以上研究,設計了均勻可調紅外輻射源原理樣機,并進行了驗證實驗,結果證明通過控制推拉窗開口寬度,能夠較好的實現(xiàn)對輻射量的均勻控制。
[Abstract]:Aiming at the radiation control problem of infrared radiation source, a uniform and adjustable infrared radiation source scheme is designed. The optical properties of parabolic cylindrical mirror are analyzed, the radiation model after reflection is given, and the collimating effect of parabolic cylindrical mirror is simulated. It is proved that the parabolic cylindrical mirror has a good convergence effect. In this paper, the radiation regulation effects of shutters and push-pull windows are compared, and the variation model of light transmission area of two-way push-pull windows is deduced, and the linear relationship between the width of the window opening and the radiation power is obtained. Based on the above research, a uniform and adjustable infrared radiation source prototype is designed and verified. The results show that the uniform control of radiation amount can be achieved by controlling the width of the opening of the push-pull window.
