| Zusammenfassung: | An optical navigation system and method of estimating motion uses a plate with an aperture, a photodetector and an optical system for optical lift detection. The optical system is configured to direct an input light to a target surface through the aperture of the plate and to direct the input light reflected from the target surface and transmitted back through the aperture of the plate toward the photodetector to be detected by the photodetector for lift detection. |
