Fiber optic devices for image transmission
光纤传像元件基于光的全反射原理，由两种或两种以上特定光学纤维规则排列而成，将把图像从输入端面传输到输出端面的图像传输元件。
Fiber optic devices for image transmission based on the principle of total reflection of light, which is composed of two or more specific optical fibers arranged in a angular way to transmit images from the input end face to the out end face.
