ow does white light scanning work?
I know the system is used in industry to measure parts for dimensions like diameter, size.

I know there is a white light source. There is a camera mounted at a known angle relative to the white light source. I was told the signal is obtained from the center of energy of the white light source which means the system can measure features smaller than the size of t he white light dot. Also the white light source can be targeted at surfaces up to 85 degrees form perpendicular and still yield credible data.

does anyone have more insight regarding this ?
