1. A method of operating a measurement device, the method comprising:
performing a first measurement, by emitting a first beam of light having a first wavelength, at a first instant of time;
introducing a first passive period of time after the first measurement;
performing a second measurement, by emitting a second beam of light having a second wavelength, at a second instant of time, wherein the second wavelength is different than the first wavelength and the second instant of time is after the first passive period of time; and
introducing a second passive period of time after the second instant of time, wherein the second passive period of time is different from the first passive period of time;
detecting noise signals during one or more of the first passive period of time and the second passive period of time;
recording a count of photons in the detected noise signals;
determining an intensity of the noise signals based on the count of photons; and
adjusting intensities of the beam of lights emitted during the first measurement and the second measurement based on the intensity of the noise signals.
