Abstract:
An optical navigation module includes a light source, a light transmission window having a navigation surface, a first light shield configured for blocking the ambient light and absorbing the scattered light, a sensor configured for detecting light from the light transmission window and a second light shield located between the light source and the sensor and configured for blocking the direct light from the light source to the sensor. The light transmission window includes at least one refraction surface. The refraction surface is in the light path from the light source to the sensor.
