A brief report is given of some observations made during an extended investigation into the subjective image quality of telescopes. For part of the work, a device was required that would indicate directly to an observer the accuracy of eye position, both laterally and longitudinally, with respect to an artificial pupil. This device is described. During use it was observed that the point image produced by the device approximately tracked the eye rotation. This unanticipated property is explained and a different optical arrangement is suggested in order to exploit and enhance this tracking property. The reason for drawing attention to the technique is not only that there may be similar situations in which such devices may be used but also that the tracking property may have other applications, perhaps in a teaching or clinical context.
本文简要报告了在对望远镜主观图像质量进行深入研究期间所做的一些观察。在部分工作中，需要一种能直接向观察者指示眼睛相对于人工瞳孔在横向和纵向位置准确性的装置。本文对该装置进行了描述。在使用过程中观察到，该装置产生的点图像大致跟踪眼睛的转动。文中解释了这一意外特性，并提出了一种不同的光学布置，以利用和增强这种跟踪特性。提请关注该技术的原因不仅在于可能存在使用此类装置的类似情况，还在于这种跟踪特性可能有其他应用，或许在教学或临床环境中。
