一、色觉的概念色觉是不同波长或光谱组成的光作用于视觉系统的一种主观感觉。视觉系统所能感受的只是电磁波长为 3 80～ 760ｎｍ的部分 ,这一区域的电磁波通常称为可见光。光源或各种物体表面的反射光进入我们的视觉器官—眼睛 ,由眼的屈光系统成像在视网膜上。在视网膜的光感 First, the concept of color vision Color vision is the composition of light of different wavelengths or spectrum of light acting on the visual system of a subjective feeling. What the visual system can feel is only the part of the electromagnetic wavelength of 380 ~ 760nm, the electromagnetic waves in this area are usually called visible light. Reflected light from the surface of a light source or various objects enters our visual organ, the eye, and is imaged by the eye’s refractive system on the retina. Light perception in the retina
