DESCRIPTION: The probe, to be designed for insertion in the external ear canal, would consist of two-single mode fibers, conducting light from a laser, a bundle of glass fibers carrying the interference image from a semi-transparent screen to the photodiode array, a pressurizer tube, a clear channel for acoustic stimulation and lenses to focus the light reflected from the tympanic membrane upon the semi-transparent screen, creating the interference image in conjunction with the reference beam.

描述：探头设计用于插入外耳 运河，将由两个单模光纤组成，从一个 激光，一束玻璃纤维，携带来自 光电二极管阵列的半透明屏幕、稳压管、 用于声音刺激的清晰通道和用于聚焦光线的透镜 从鼓膜反射到半透明屏幕上， 结合参考光束创建干涉图像。
