The effective-area method is a new way to measure aperture area. It defines aperture area by directly using the beam-limiting effect of the aperture in radiometric measurement. Due to the special structure of the measurement device, it is necessary to find a suitable method to design the detection system. In this paper, the measurement system model is constructed in the TracePro program. The real circumstances of light propagation for the measurement beam are simulated, and the responses of the detector are given. It is proved that the relative change in the detector response is the lowest when the detector is at the position of 132°. And this is the best structure design of the detection system. The experimental results are designed to verify the feasibility of the structure design of the detection system.
有效面积法是一种测量孔径面积的新方法。它通过在辐射测量中直接利用孔径的光束限制效应来定义孔径面积。由于测量装置的特殊结构，有必要找到一种合适的方法来设计检测系统。本文在TracePro程序中构建了测量系统模型。模拟了测量光束光传播的实际情况，并给出了探测器的响应。结果表明，当探测器位于132°位置时，探测器响应的相对变化最小。这就是检测系统的最佳结构设计。设计实验结果以验证检测系统结构设计的可行性。
