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 ...
Areal filters are defined for surfaces measured either by lateral scanning instruments or optical profilometers. Parts related to areal filters are: ISO 16610-60: Linear areal filter: Basic concepts (published in 2015) ISO 16610-61: Linear areal filter: Gaussian filters (published in 2015) ISO 16610-62: Linear areal filter: Spline filters

Figure 3. White light interferometric microscope. White-light interferometry scanning (WLS) systems capture intensity data at a series of positions along the vertical axis, determining where the surface is located by using the shape of the white-light interferogram, the localized phase of the interferogram, or a combination of both shape and phase.
Another disadvantage is that profilometers have difficulty detecting flaws of the same general size as the roughness of the surface. [1] There are also limitations for non-contact instruments. For example, instruments that rely on optical interference cannot resolve features that are less than some fraction of the operating wavelength.
An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are measured against prescribed limits .
