1. A circadian sensor system comprising:
a low-resolution incident-light spectral sensor that provides low-resolution incident-light spectra, the low-resolution incident-light spectra having a low incident-light spectral resolution;
a data analyzer for converting the low-resolution incident-light spectra to high-resolution source circadian spectra of a circadian light source, the high-resolution source circadian spectra having a high source circadian spectral resolution, the high source circadian spectral resolution being higher than the low incident-light spectral resolution, the converting being based on:
a circadian low-resolution source signature of the circadian light source for determining low-resolution source spectra of the circadian light source based on the low-resolution incident-light spectra, the low-resolution source signature having a low source signature spectral resolution that is lower than the high source circadian spectral resolution, and
a high-resolution source circadian profile for determining the high-resolution source circadian spectra based on the low-resolution source spectra, the high-resolution source circadian profile having a high source profile spectral resolution that is higher than the low source signature spectral resolution and higher than the low incident-light spectral resolution; and
a wireless communications interface for wirelessly transmitting spectral data representing or based on the high-resolution source circadian spectra.
