Abstract:

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.

Abstract:

An electronically scanning emitter array that includes a two-dimensional array of light emitters arranged in k emitter banks. Each of the k emitter banks can include a subset of the light emitters in the two-dimensional array and can be independently operable to emit light from its subset of emitters. The electronically scanning emitter array can further include first and second capacitor banks coupled to provide energy to the two-dimensional array of light emitters and emitter array driving circuitry coupled to the first and second capacitor banks and to the k emitter banks. Each of the first and second capacitor banks can include at least one capacitor. The emitter array driving circuitry can include a first high-side switch coupled between the first capacitor bank and a voltage source, a second high-side switch coupled between the second capacitor bank and the voltage source, and k/2 low-side switches coupled between the k emitter banks and ground; and the emitter driving circuitry can be configured to fire one emitter bank in the k emitter banks at a time according to a firing sequence until each of the k emitter banks are fired.
