1.视场问题的分类 (1)确定眼在什么范围内能通过平面镜看到完整或局部的像. (2)眼在确定的位置能通过平面镜看到像的哪些部分. 问题(2)可应用光路可逆,把眼看作“发光体”,其通过平面镜能“照亮”的区域,即为眼所能看到的区域.这也是能看到眼的像的观察范围,从而转化为问题(1). 2.确定视场的方法先作出像的位置,再作出边界光线. 3.确定视场的关键
1. Classification of Field of View Problems (1) Determine the extent to which the eye can see a complete or partial image through a plane mirror. (2) Which part of the image can be seen through the plane mirror at a certain position in the eye. Problem (2) may be The application of the light path is reversible and the eye is seen as a “light”. The area that can be “illuminated” by the plane mirror is the area that can be seen by the eye. This is also the range of observation that can see the image of the eye, which translates into problems ( 1). 2. Determine the field of view by first making the position of the image, and then make the boundary light. 3. Determine the key to the field of view
