Fiber optic inverter is used for optical image information transmission. It can invert the image to 180o.The image which is pressed against one end of the FOI will be resolved to the correspondent pixels by millions of fibers, then the regular arrayed fibers will transmit the pixels information correspondently to the other end of FOI, the pixels are reversed to 180° with the inversion of fibers while transmitting and combined to 180° inverted image on the output window.
Feature: Inverting the image, High transmission efficiency, Clear image transmission(High resolution), “Zero” optical distance.
Application: As the output window element, FOI can be applied to the image intensifier of the low-light-level night vision instrument.
