<p>Various embodiments of optical mice are disclosed. One embodiment comprises a light source configured to emit light having a wavelength in or near a blue region of a visible light spectrum toward a tracking surface at an oblique angle to the tracking surface, an image sensor positioned to detect non-specular reflection of the light from the tracking surface, and one or more lenses configured to form a focused image of the tracking surface on the image sensor at the wavelength in or near the blue region of the visible light spectrum emitted by the light source. Further, the optical mouse comprises a controller configured to receive image data from the image sensor and to identify a tracking feature in the image data.</p> |
