WebTo capture height data, the laser is scanned in the XYZ directions across the surface of the sample, and the reflected light intensity is measured. The result is a high-resolution, large depth-of-field, color image with nanometer-level height resolution for accurate profile and roughness measurements. A profilometer is a measuring instrument used to measure a surface's profile, in order to quantify its roughness. Critical dimensions as step, curvature, flatness are computed from the surface topography. While the historical notion of a profilometer was a device similar to a phonograph that measures a surface as the surface is moved relative to the contact profilometer's stylus, this notion is changi…

WebProfile measurement of deep drawn products can be done by visualizing the part against its CAD data, while spring back can be analyzed by measuring the difference from cross-sections. In addition, hand tools cannot capture the thickness of a bent part or changes in thickness caused by metalworking, but a 3D part scanner can capture the rate of ... Beam profilers generally fall into two classes: the first uses a simple photodetector behind an aperture which is scanned over the beam. The second class uses a camera to image the beam. The most common scanning aperture techniques are the knife-edge technique and the scanning-slit profiler. The former chops the beam with a knife and measures the transmitted power as the blade cuts through the beam. The measured intensity versus knife position yields a curve that is … fnf little brother mod
