Embodiments of diffuse optics in an optical mouse are disclosed. In one embodiment, an optical mouse comprises a light source configured to emit light toward a tracking surface, an image sensor, an optical diffuser dis-posed optically upstream of the tracking surface and con-figured to diffuse light from the light source that illumi-nates the tracking surface, and a controller configured to receive image data from the image sensor and to identify a tracking feature in the image data.

L'invention concerne des modes de réalisation d'une optique diffuse dans une souris optique. Dans un mode de réalisation, une souris optique comprend une source lumineuse configurée pour émettre de la lumière vers une surface de tracking, un capteur d'image, un diffuseur optique disposé optiquement en amont de la surface de tracking et configuré pour diffuser la lumière de la source lumineuse qui éclaire la surface de tracking, et un contrôleur configuré pour recevoir des données d'image de la part du capteur d'image et pour identifier une caractéristique de tracking dans les données d'image.
