An optical sensor is a sensor that measures on the basis of optical principles. It has many advantages such as non-contact and non-destructive measurement, almost no interference, high-speed transmission, telemetry, and remote control.
Mainly include optical measuring instruments, laser interferometers, gratings, encoders, optical fiber optical sensors and instruments. It is primarily designed to detect the presence of objects, or to perform various industrial, automotive, electronics, and retail automated motion detection.
The finger is pressed on one side of the glass plane, and an LED light source and a CCD camera are mounted on the other side of the glass. The light beam emitted by the LED illuminates the glass at a certain angle, and the camera is used to receive the light reflected from the glass surface. The ridge line on the finger is in contact with the glass surface, and the valley line is not in contact with the glass surface. Therefore, the light irradiated on the surface of the glass where the fingerprint ridge line contacts is diffusely reflected, and the light irradiated on the glass surface corresponding to the fingerprint valley line is It is totally reflected so that in the image captured by the CCD camera, the portion corresponding to the fingerprint ridgeline is darker, and the portion corresponding to the fingerprint valley line is lighter in color.
