Light Scanning White light

AI Thread Summary

White light scanning utilizes a white light source and a camera positioned at a specific angle to accurately measure dimensions such as diameter and size. The system captures data from the center of energy of the white light, enabling it to measure features smaller than the light dot itself. It can effectively scan surfaces at angles up to 85 degrees from perpendicular while still providing reliable measurements. This technology is widely used in various industries for precise dimensional analysis. Further insights into its applications and technical specifications would enhance understanding of its capabilities.

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 ?
