<p>A tunable light source system with wavelength measurement capability for a hyper-spectral imaging system is disclosed. A method includes reference filtering a portion of a tunable light beam while tuning the center wavelength, detecting with at least one photodetector the reference-filtered tunable light beam and generating therefrom at least one detector signal that varies with the center wavelength, and determining a tunable center wavelength based on the at least one detector signal.</p> |
