Abstract: An illustrative optical measurement system includes a light source configured to emit light directed at a target within a user, the target covered by a superficial layer, and an array of photodetectors configured to detect photons of the light after the light is scattered. The system further includes a processor configured to record, during a first and a second time period, a first and a second set of timestamp symbols, respectively, based on a first and a second subset of the array of photodetectors detecting a first subset of the photons that are scattered by the superficial layer and a second subset of the photons that are scattered by the target and the superficial layer, respectively. The processor is further configured to filter, based on the first set of histogram data, the second set of histogram data, and determine, based on the filtering, histogram data corresponding to the target.

Abstract: An optical measurement system includes a first wearable module comprising a first source configured to emit a first light pulse sequence comprising a plurality of light pulses and a first plurality of detectors configured to detect photons from the first light pulse sequence. The system further includes a second wearable module comprising a second source configured to emit a second light pulse sequence comprising a plurality of light pulses and that is time interleaved with the first light pulse sequence, and a second plurality of detectors configured to detect photons from the second light pulse sequence. The system further includes a control circuit configured to control light pulses emitted by the sources in accordance with time and/or frequency division multiplexing heuristics.

Abstract: An optical measurement system includes a first light source configured to emit a first light pulse toward a target, a second light source configured to emit a second light pulse toward the target, a first detector, a second detector, and a processing unit. The processing unit is configured to determine a plurality of temporal distributions of photons included in the first light pulse and the second light pulse and detected by the first detector and the second detector after the photons are scattered by the target. The processing unit is further configured to determine, based on the plurality of temporal distributions, a distance between the first light source and the second detector.

Abstract: A wearable module for use in an optical measurement system includes a light guide configured to receive a light pulse from a light source and guide signal photons included in the light pulse toward a target within a body of a user, and a light diverter configured to divert reference photons included in the light pulse toward at least one detector configured to detect the reference photons.
