Abstract
Techniques for determining dynamically the intensity of the reflection from a transmissive cover and neutralizing it so as to improve the accuracy of depth measurements. Depth measurements of light modulation at multiple frequencies—which also can be used for depth disambiguation—are obtained and used to decouple the information to estimate the intensity of the signal reflected by the transmissive cover itself or a smudge on the transmissive cover, and the intensity of the signal reflected by the target object.
