The image which is pressed against one end of fiber optic inverter (FOI) is resolved to the correspondent pixels by millions of fibers, and the pixel information is transmitted to the other end of the FOT one by one through the total reflection of light. The pixels are enlarged or reduced with the fiber diameter and are imaged at the output end according to the original arrangement.

At present, cars on the market are becoming more and more intelligent, and tend to be highly combined with software and hardware and interconnected with various functions.

This technique is a new fingerprint scanner. In this technique, Fiber Optic Plate (FOP) can transmit the fingerprint signal from the top surface to the other surface that coupled with sensor.
