1. An apparatus comprising:

  • an emitter;

    a detector that detects emissions from the emitter and, simultaneously, detects emissions from at least one source other than the emitter; and

    circuitry that distinguishes between the emissions from the emitter and the emissions from the at least one source other than the emitter that are simultaneously detected by the detector, wherein the emissions from the emitter and the emissions from the at least one source other than the emitter that are detected by the detector comprise emissions of electromagnetic radiation that overlap in frequency.
