Surface metrology is the measurement of tiny features on surfaces and is a branch of metrology. Surface primary shape, surface fractal and surface finish (including surface roughness) are the parameters most commonly associated with this field. It is important to many disciplines and is known for ma

3D object scanningIn the field of 3D object scanning, laser scanning (also known as lidar) combines the controlled steering of a laser beam with a laser rangefinder. By taking distance measurements in every direction, the scanner can quickly capture the surface shape of objects, buildings and landsc

Laser scanning is the controlled deflection of a visible or invisible laser beam. [1] Scanning laser beams are used in some 3D printers, rapid prototyping, materials processing machines, laser engraving machines, ophthalmic laser systems for the treatment of presbyopia, confocal microscopes, laser p
