<正> 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

Scotopic relative spectral luminous efficiency functions have been determinedwith brightness matching method at 8.8×10-4（cd）/m2. There was a dim redfixation point on the upper edge of a visual field which had a diameter subtending20°at the eye, and was divided vertically into two equal parts, one was thestandard, and the other illuminated with various comparison lights. Two agegroups of subjects were used, one below 30 and the other above 30 years,including 13 and 11 normal vision subjects respectively. 14 points were selectedfor measurement in wavelength ranging from 420 to 640 nm. The results indicated: 1) The average maximum spectral sensitivity of the subjects equals to 515nm. It is slightly higher than that of CIE V′λ which occurs at about 507 nm 2) The comparison between two age groups shows that V′λ values decreasein the short wave side of spectrum with the increase of age.
