Abstract
There is provided an optical navigation device including a substrate, a light sensor, a first light source, a second light source and a light directing member. The light sensor is arranged on the substrate and has a field of view (FOV) perpendicular to the substrate. The emission light of the first light source forms a first illumination light beam after passing the light directing member. The emission light of the second light source forms a second illumination light beam after passing the light directing member. A first crossover region of the first illumination light beam with the FOV is closer to the substrate than a second crossover region of the second illumination light beam with the FOV.
