Optical mouse uses a red LED as a replacement ball mouse. Light from this LED will be reflected by the surface of the table / pedestal to the sensor CMOS (Complimentary Metal Oxide Semi-konductor). The sensor then sends a picture of the surface to the Digital Signal Processor (DSP).
DSP will analyze the images before and determine the distance obscuring the mouse which is then sent to computer. Based on these data, the computer will shift the mouse cursor position on screen. If now there is kind of an optical mouse that can run on any base surface, first optical mouse to be run at a special mouse pad that has a pattern of lines of this box which will break the pattern of light reflection LED.Based on LED flame-off, the computer will know the distance obscuring the mouse. But, mouse type is more difficult to use and can not be used without special mouse pad.
Advantages compared to optical mouse mouse optimekanik:
1. No part to be moved, so there is no possibility of failure of the round.
2. Because fully closed, not allowing dust into the mouse.
Resolution tracking softer light so that movement of the mouse cursor on the screen is also more subtle.
