texture of surface roughness measurement with optical sensor?
How can we measure the roughness of the metal surface in the range 0.5mm so i have dat 1microns solution with optical mouse sensor that can do, but hw? I need something in detail and depth …..
You can be that in something here. If you read the amount of reflected light, you can know how something harsh, but would first have to take into account the amount of light absorbed by the color of the surface, then calculate much more light is reflected or not reflected in the roughness of the surface. I'm thinking this would be very difficult, however, if it was to read a single type of thing, in the form of rolled steel plates newly … of course, so no rust or anything, it should work. This would always form the same rate of absorption of the color, so any difference can be attributed to surface roughness! Neat Idea!
