Abstract
An optical measurement system includes a light source configured to emit a first light pulse and a second light pulse toward a target, a detector, and a processing unit. The first light pulse has a first wavelength and the second light pulse has a second wavelength different from the first wavelength. 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 detector after the photons are scattered by the target, and determine, based on the plurality of temporal distributions and a source-detector distance estimation model, a distance between the light source and the detector.
