Abstract
An optical ranging system includes a support, a light emitter mounted on the support, and a time-of-flight ('TOF') sensor chip mounted on the support. The TOF sensor chip, for example, includes at least one main pixel and at least one reference pixel in a semiconductor substrate. A barrier that is substantially non-transparent to light emitted by the light emitter separates the at least one reference pixel from the at least one main pixel. The optical ranging system also includes features for reducing optical cross-talk between the light emitter and the pixels of the TOF sensor.
