An application of an MOS-type solid-state imaging sensor to a television pupillometer is described. Its advantages over the conventional image-tube pupillometers using silicon vidicons are demonstrated with special emphasis on its excellent dynamics performance. Design considerations for an MOS-type solid-state TV camera and the schematic diagram of a pupillometer which detects the horizontal pupillary diameter are presented. Two methods of infrared illumination giving no heat sensation to subjects are also proposed: the effective use of an aquatic filter and solid-state illumination utilizing i.r.-LEDs.
本文描述了一种MOS型固态成像传感器在电视瞳孔计中的应用。文中特别强调了该传感器相对于使用硅光导摄像管的传统像管式瞳孔计的优势，即其出色的动态性能。文中介绍了MOS型固态电视摄像机的设计考量以及用于检测水平瞳孔直径的瞳孔计的原理图。还提出了两种不会给受试者带来热感的红外照明方法：有效利用水滤光片和利用红外发光二极管的固态照明。
