Abstract
An illustrative optical measurement system may include a wearable assembly comprising a plurality of modules each configured to fit within a different slot of the wearable assembly. The plurality of modules may include a module that comprises first and second light sources each configured to emit light directed at a target and a set of detectors configured to detect arrival times for photons of the light emitted by the first and second light sources. A ratio of a total number of the detectors to a total number of the light sources is at least two to one.
