Abstract

See full text

An optical measurement system includes a photosensor that includes one or more photosensitive elements. Each of the photosensitive elements may generate signals when a photon is detected, and the number of photons detected for each photosensor may be accumulated in an integration register. The integration register may accumulate photon counts independent of a parallel data path that stores photon counts in time bins based on photon arrival times to form a histogram representation. The total photon count in the integration register can be used to estimate ambient background light and properly set signal thresholds for detecting reflected light signals represented in the histogram.
