动态测量瞳孔测试仪

A Dynamic Measuring Instrument for Pupil of Eye

论述了直接在明室中动态测量瞳孔测试仪的研制．采用近红外摄象、瞳孔视频信号处理、电子窗口等技术分析瞳孔视频信号的处理，保证动态瞳孔测试仪能够在明室或暗室中测量瞳孔的直径和面积．此外，在个别受试者的眼皮遮去部份瞳孔时，该测试仪也能进行正确测量．

The development of the dynamic pupil measuring instrument used directly in a bright room is discussed.By adopting the techniques of near infrared photography, pupil video signal treatment and electronic windows,etc.,and by analysing pupil video signaltreatment, the instrument can be ensured to measure the diameters and areas of pupils in a bright or dark room.Besides,it can also measure pupils correctly when they are partly covered by eyelids.
