一、引 言 人眼作为光接受器,对于可见光谱内的不同波长的辐射有不同的视亮度或感受性。随着光照水平的变化,人眼的这种光谱感受性又有明显的变化:在明视条件下,正常人眼最敏感的部位在黄绿区内;在暗视条件下,敏感峰值向短波段推移,在蓝绿区。这种现象称为朴金耶(purkinje)位移。它是由网膜机能的双重性所决定的——明视觉主要是锥体
I. INTRODUCTION The human eye as a light receptor has different brightness or receptivity to radiation of different wavelengths in the visible spectrum. With the change of light level, the spectral sensitivity of the human eye has obvious changes: under the condition of bright vision, the most sensitive part of the normal human eye is within the yellow-green zone; under the dark vision condition, the sensitive peak is shifted to the short wave band Going in the blue-green zone. This phenomenon is called purkinje displacement. It is determined by the dual nature of the function of the omentum - the main visual point is the cone
