An analysis is presented of the optical factors influencing photoreceptor excitation. Small receptors are considered and the incident light is focussed onto them by a lens. The theoretical principles involved are outlined and explained in simple terms and by using analogies, so that they are also accessible to the nontheoretician. System parameters relevant to the fly are used as a basis for study. The theory is used to discuss the choice of lens parameters, the effects of defocussing and chromatic aberration. The emphasis is on results and in all cases graphs are presented so that magnitudes and trends are readily appreciated.
本文对影响光感受器激发的光学因素进行了分析。研究了小型感受器，并通过透镜将入射光聚焦到这些感受器上。文中以简单易懂的方式并借助类比，概述和解释了所涉及的理论原理，以便非理论专业人员也能理解。以与果蝇相关的系统参数作为研究基础。该理论用于讨论透镜参数的选择、散焦和色差的影响。重点在于研究结果，所有情况下均给出了图表，以便直观地了解其大小和趋势。
