Optical navigation device |
摘要 |
<p>The invention provides an optical navigation device comprising: an image sensor with an imaging surface; a laser; and an optical waveguide layer having an exposed user surface and a total internal reflection (TIR) surface on the underside of the exposed user surface. The waveguide layer, laser and image sensor are together arranged to direct radiation emitted by the laser onto the imaging surface at least partly by total internal reflection by the TIR surface.</p> |
