How do optical mouse woks??

In this article we had explained how do an optical mouse works, This is a simple topic as compared to other computer hardware.

Optical mouse works by using a tiny low-resolution video camera (embedded in a sensor) to take successive images of the surface on which the mouse operates. It uses an LED (light-emitting diode) which illuminates red light (generally) onto the surface underneath which is reflected back and fine-tuned before getting picked up by the sensor. A plastic lens collects the reflected light and forms an image on a sensor.

     

If you were to look at the image, it would be a black-and-white picture of a tiny section of the   surface. The sensor continuously takes pictures as the mouse moves. The sensor takes pictures quickly—1500 pictures (frames) per second or more—fast enough so that sequential pictures overlap.

The rest of the work is taken care by the Optical Navigation engine. Through a patented image-processing algorithm, the optical navigation engine identifies common features between the captured frames and determines the distance between them. This information is then translated into X and Y coordinates to indicate mouse movement.

        

We hope this article was use full for you & was able to clear the doubts you had about the optical mouse.
