Abstract
An illustrative optical measurement system may include a wearable assembly configured to be worn by a user and comprising a plurality of light sources each configured to emit light directed at a target and a plurality of detectors configured to detect arrival times for photons of the light after the light is scattered by the target, wherein a ratio of a total number of the detectors to a total number of the light sources is at least two to one.
