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.

An optical measurement system comprising:
- 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 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, and
- determine, based on the plurality of temporal distributions, a source-detector distance between the first light source and the second detector.
A method comprising:
- directing, by an optical measurement system, a first light source to emit a first light pulse toward a target;
- directing, by the optical measurement system, a second light source to emit a second light pulse toward the target;
- determining, by the optical measurement system, a plurality of temporal distributions of photons included in the first light pulse and the second light pulse and detected by a first detector and a second detector after the photons are scattered by the target;
- and
- determining, by the optical measurement system based on the plurality of temporal distributions, a source-detector distance between the first light source and the second detector.
