Product Description

Optical Finger Navigation：IR LED within the sensor will send out infrared optical fiber, which could pass through IR Cover by prismatic refraction. Then it will reflect on the fingers, pass through optical lens and form image in light induction component (micro imager). With interior specified image analysis chip (DSP, namely digital microprocessor), it can analyze and process a series of images in the path. After analyzing the moving position Changes of these characteristic points, it could judge displacement direction and distance. Thus localization is completed.
