The fiber v-groove assembly array can also be used to transmit images directly. The end faces of many optical fibers are arranged into the required geometric shapes in a certain order to form the fiber V-groove array. The fiber positions at both ends of the array correspond to each other. One fiber in the array is equivalent to a pixel. And the optical image at the one end of the fiber V-groove array will be reproduced at the other end. This principle is applied in all kinds of medical optical fiber endoscopes.
