折射现象中所成的虚像在不同位置观察其视深度是不同的,偏离正上方越多,其视深度越浅.在介质正上方垂直观察时:视深度=实际深度/折射率;我们还可以拓展到在正下方垂直观察介质上方的物体的视高问题:视高度=实际高度×折射率;其推导原理是一样的.下面主要以视深为例分析几种常见的情形:一、以平面为观察界面例1 一个同学想知道穿衣镜玻璃的厚度,他用手指接触玻璃的表面,从正前方观察镜子中
The virtual image formed by the refraction phenomenon has different apparent depths at different positions. The more the deviation is from the top, the shallower the apparent depth. When viewed vertically above the medium: apparent depth = actual depth/index; we can also Expand to the vertical height of the object directly above the medium just below: As the height = the actual height × the refractive index; the derivation principle is the same. The following focuses on the depth of field as an example to analyze several common situations: To observe the interface Example 1 A classmate wants to know the thickness of the mirror glass. He touches the surface of the glass with his fingers and observes the mirror from the front.
