The creative point of this dissertation consists firstly in that monochromatic stimuli instead of combined spectral power distribution were used as visual object, and spectral luminous efficacy curves were drawn from the performance-based method; Comparison between performance-based method and brightness-matching method was then done and therefore connection between these two methods was developed; One more creative point is that the analysis based on the theory of neurophysiology and psychophysics leads to the conclusion that contribution of the colour channel during visual information processing is reflected from performance-based method, which should be considered when CIE develops the new mesopic photometry system.
论文的新颖之处在于实验中使用了单色光谱代替复合谱或物体色作为视觉目标,在分析中间视觉状态下视觉功能的光谱响应特性的基础上反推了人眼的光谱光视效率函数;论文更进一步验证了基于视觉功能法和传统的视亮度匹配法之间的联系,在两种方法之间构造了一座桥梁,为基于视觉功能法的使用初步建立了理论依据;同时论文创新地采用心理物理学的方法进行实验和结合物理学和视神经生理学的知识对实验结果进行分析,从而从视觉信息处理的神经机制层面证明了基于视觉功能法获得的结果包含了视觉颜色通道效应,并对CIE在建立新的中间视觉光度学系统时要充分考虑这一视觉颜色通道的影响提出了建议。
