1. An apparatus comprising:

  • a first optical source disposed at a first position and configured to emit a first optical signal of a first wavelength;

    an arrangement of optical detectors, at least some of which are positioned at different distances from the first optical source, including a first subset of multiple optical detectors positioned a first distance from the first optical source and a second subset of multiple optical detectors positioned a second distance greater than the first distance from the first optical source, wherein the first subset of multiple optical detectors and the second subset of multiple optical detectors are configured to receive the first optical signal,wherein a first optical detector of the first subset of multiple optical detectors is configured to produce a first output signal indicative of a first received optical intensity of the first optical signal,wherein a second optical detector of the second subset of optical detectors is configured to produce a second output signal indicative of a second received optical intensity of the first optical signal, andwherein a third distance between the first optical detector of the first subset of multiple optical detectors and the second optical detector of the second subset of multiple optical detectors is a smallest distance from among a plurality of distances between the first optical detector and the multiple optical detectors of the second subset; and

    a processor coupled to the first and second subsets of multiple optical detectors and configured to receive from the first and second subsets of multiple optical detectors signals detected by those detectors, including the first output signal from the first optical detector and the second output signal from the second optical detector, the processor being further configured to process in combination the first output signal and the second output signal.
