Abstract
An apparatus and method for a spectrally stable light source is disclosed. An excitation source provides a spectrally stable light within a predetermined bandwidth. The spectrally stable light is directed at a reflective target. A light sensor receives reflected light from the surface of the target through the fiber optic cable and generates reflected spectral data. A computer receives the reflected spectral data and calculates a signal based on the reflected spectral data.
