Abstract: An analog silicon photomultiplier system includes at least one analog pixel comprising a plurality of analog photodiodes (APDs), and a capacitor, a signal generator, a phase detector, and a compensation network. The signal generator is configured to generate and propagate a sinusoidal signal concurrently along first and second transmission lines. A capacitor is loaded on the first transmission line when an APD corresponding to the capacitor detects a photon. The phase detector is coupled with the first and second transmission lines, determines a phase difference between the first transmission line and the second transmission line and calculates a number of APDs that have fired from the phase difference. The compensation network is coupled with the second transmission line and the phase detector, and comprises a plurality of compensation capacitors, wherein the compensation capacitors are loaded on the second transmission line in proportion to the number of APDs that have fired.

Abstract: A light sensor and light sensing system to detect an intensity of incident light and an angle of incidence of the incident light. The light sensor includes a dielectric layer, a plurality of photo detectors coupled relative to the dielectric layer, and a plurality of stacks of opaque slats embedded within the dielectric layer. The dielectric layer is substantially transparent to the incident light. The photo detectors detect the incident light through the dielectric layer. The stacks of opaque slats are approximately parallel to an interface between the dielectric layer and the photo detectors. The stacks of opaque slats define light apertures between adjacent stacks of opaque slats. At least some of the stacks of opaque slats are arranged at a non-zero angle relative to other stacks of the opaque slats.
