The resolving power in monocular, foveal vision was found to depend on the size of a white light source made of two white rectangles separated by vertical black bar. The question arises whether the wavelength of light influences this dependence. An experiment was done on three subjects using six monochromatic lights the range 450-625 nm, and white light for control measurements. The diagram of the dependence of the minimal angle of resolution on the source size takes the shape of a biphasic curve, i.e. decreasing and constant function. The wavelength was found to have no impact on the curve shape or values. The data points obtained for white light coincide with those for monochromatic lights. The results confirm a thesis that all three colour mechanisms in the human visual system are stimulated and are active in spatial summation processes, but to a degree conditioned by a spectral sensitivity of the particular colour apparatus. It was confirmed that all colour mechanisms have potentially the same acuity but the axial chromatic aberration causes observed reduction of acuity.
研究发现，单眼中央凹视觉的分辨力取决于由两个白色矩形组成、中间有垂直黑色条纹分隔的白色光源的大小。由此产生的问题是，光的波长是否会影响这种依赖性。对三名受试者进行了一项实验，使用了六种波长范围在450 - 625纳米的单色光，并使用白光进行对照测量。分辨力最小角度与光源大小的依赖关系图呈双相曲线形状，即递减函数和常数函数。结果发现，波长对曲线形状或数值没有影响。白光获得的数据点与单色光的数据点一致。这些结果证实了一个论点，即人类视觉系统中的所有三种颜色机制都会被刺激并在空间总和过程中起作用，但在一定程度上受特定颜色器官的光谱敏感性制约。研究证实，所有颜色机制潜在地具有相同的敏锐度，但轴向色差导致观察到的敏锐度降低。
