1. A physiological sensor comprising:

  • a broadband light emitter adapted to transmit light across a range of wavelengths;

    an optical filter associated with the broadband emitter, wherein the optical filter is adapted to substantially pass light transmitted from the broadband light emitter at a specific wavelength or at a subset of the range of wavelengths through the optical filter and to substantially block light at all other wavelengths from passing through the optical filter; and

    a light detector adapted to receive the light passed through the optical filter.
