The idea is to send a laser beam on a surface and measure the DIFFERENCE between
origin beam and reflected beam.
The difference of wavelength should give a hint to the color of the surface, the
difference of intensity a hint to the brightness.
Question is, wether this can be implemented in a real project. I yes, this could
even be used as a high precision scanner device (on a 2-axis system, like a
plotter).
The clue is that a differential signal would keep it's absolute values as the
reflected beam fluctuates equally to the origin beam.
