三、AR 谱分析(一)概述什么是谱分析,让我们举一个简单的生活实例来说明。例如人们用眼睛观察物体,可以辨别出物体的明暗,即眼睛可识别来自物体反射光的强弱,眼睛也可以辨别物体不同颜色,而颜色是反映物体反射光不同频率。因此人们的眼睛具有分析物体反射光强弱及频率的本领,即眼睛具有简单的谱分析能力。光线是一种能量,讯号也是一种能量,但眼睛则无能为 Third, AR spectral analysis (a) Overview What is spectral analysis, let us give a simple example of life to illustrate. For example, people can observe the light and darkness of the object by observing the object with the eye, that is, the eye can recognize the intensity of the light reflected from the object, the eye can also distinguish the different colors of the object, and the color reflects the different frequencies of the reflected light of the object. Therefore, people’s eyes have the ability to analyze the intensity and frequency of reflected light of an object, that is, the eyes have a simple spectral analysis ability. Light is a kind of energy, the signal is also a kind of energy, but the eyes are incompetent
