... unless somebody removed it deliberately...
With a homemade reflection detector, I doubt this will give enough contrast, especially if the paint is glossy. Also, it might be not "black" enough in the chosen wavelength; but that's only a minor issue. However, after reflection detection with larger areas is successful, this one might be attempted, too. JW PS. Erik: Please mind your and the OP's position. PS2.: Ages ago, I designed a homebrew reflectometer, too... :-) |
