光纤倒像器/ Fiber Optic Inverter/FOI
光纤倒像器是由数千万根直径为5~6μm的光导纤维规则排列并且每根纤维的输入输出端绕着器件的轴心相对扭转180°而成型的,可以将图像反转180°,使传输的图像成为倒立的图像,具有分辨率高,传像清晰,体积小,重量轻等特点。目前主要用来代替微光夜视仪中的中继透镜系统,是二代、超二代和三代微光像增强器的关键元件,也被广泛应用于需要倒像的装置中。

Product Description
FIBER OPTIC INVERTER/FOI
Fiber Optic Inverter can be used in the image inversion system. It made the input image inversion 180 in output surface, it is mainly instead of the optic-lens system in the low-light level night vision instrument. It greatly reduces the volume, weight and cost of image intensifies and miniaturizes the night vision devices. But also has the good property of resolution and the clear image transmission. It widely used in all devices requiring image inversion.
