解光学暗箱类问题应从下述三个方面考虑.1.根据题设条件。提出合理的假设.即由入射光线和出射光线的已知关系,提出假设是光的反射或折射现象.2.验证假设,确定光学元件.即依据光学原 Solve the problem of optical black box category should be considered from the following three aspects: 1. According to the title set conditions. Put forward reasonable assumptions. That is, from the known relationship between the incident ray and the outgoing ray, the hypothesis is the reflection or refraction phenomenon of the light. 2. Verify the hypothesis and determine the optical element. That is, according to the optical source.
