Optical odometry is one in which the distance traveled is measured by optical means. Optical mouse consists of a single LED (Light Emitting Diode) which it bounces the light off the surface. It also has a very small camera which takes pictures of the surface. It scans the surface 1500 times a second. The digital signal processor receives the images that have been taken from the camera and analyses them for differences. It can pick up very fine differences in the pictures and from this it can determine how far the mouse has moved across your desk and at what speed. Coordinates are then sent to the host. The DSP can detect patterns and analyze them at a very high speed. This is used for navigation.
