Theory of Operation

The sensor is based on Optical Navigation Technology.

It contains an Image Acquisition System (IAS), a Digital

Signal Processor (DSP) and USB stream output.

The IAS acquires microscopic surface images via the lens

and illumination system provided by the trim lens. The

clip and LED. These images are processed by the DSP to

determine the direction and distance of motion. The DSP

generates the

x and y relative displacement values

which are converted to USB motion data.
