描述了用于通过直接眼镜检查对已知视网膜区域进行聚焦刺激的手持光学系统。光学系统提供了可变尺寸，视网膜照明，波长和极化的时间调节刺激光束，以及视网膜照明和波长的稳定背景束。两种光束都以麦克斯韦观看率进入患者的眼睛，以精确控制刺激与背景视网膜照明的比率。刺激器 - 摩托镜允许检查者轻松补偿可变固定。
A hand-held optical system for presenting focused stimuli on known retinal areas by direct ophthalmoscopy is described. The optical system provides a time-modulated stimulus beam of variable dimension, retinal illuminance, wave-length, and polarization, and a steady background beam of variable retinal illuminance and wavelength. Both beams enter the patient's eye in maxwellian-view for precise control of the ratio of stimulus to background retinal illuminance. The stimulator-ophthalmoscope allows the examiner to compensate easily for variable fixation.
