1. A tunable spectral source, comprising:

  • multiple pixel source elements for emitting broadband light signals;

    an enclosure having a first aperture and a second aperture;

    a first mirror mounted in said enclosure for receiving and collimating said broadband light signals received through said first aperture;

    an optically diffractive element mounted in said enclosure for receiving said broadband light signals from said first mirror and diffracting said broadband light signals into spectral component signals; and

    a second mirror mounted in said enclosure for directing said spectral component signals received from said optically diffractive element so that selected ones of said spectral component signals are emitted from said second aperture based on which of said pixel source elements generate said broadband light signals.
