An optical profilometer is a non-contact method for providing much of the same information as a stylus based profilometer. There are many different techniques which are currently being employed, such as laser triangulation (triangulation sensor), confocal microscopy (used for profiling very small objects), coherence scanning interferometry and digital holography. Advantages of optical profilometers are speed, reliability and spot size. For small steps and requ… WebFeb 10, 2024 · Optical profilometry is a technique used for the topographical study of the materials surface which works on the principle of light instead of the physical probe in …
