1. A spectral measurement system comprising:
- a computer-controlled illumination system comprising;
a tunable light source configured to emit illumination light comprising a variable selected spectral output and a variable selected wavelength dependent intensity distribution toward a target material, and a controller operably connected to the tunable light source and containing computer-implemented programming configured to vary the variable selected spectral output and the variable selected wavelength dependent intensity distribution in the illumination light to provide a desired spectral output and wavelength dependent intensity distribution configured for measuring spectral properties of the target material; and
a spectral measurement sensor configured to detect light emanating from the target material and determine spectral data of the light emanating from the target material to provide target spectral data, the spectral measurement sensor operably connected to the computer-controlled illumination system to communicate the target spectral data to the computer-controlled illumination system;
wherein the controller is configured to receive the target spectral data and incorporate the target spectral data to tune the tunable light source to vary the variable selected spectral output and the variable selected wavelength dependent intensity distribution in the illumination light to enhance the desired spectral output and wavelength dependent intensity distribution of the illumination light.
