What is "profilometry"

alt. 1 The use of a technique in the measurement and profiling of an object. 2 The methodology of performing eddy current profiling of tubing. 3 The technique in which a diamond stylus, in contact with a sample, measures surface variations as a function of position. 4 The use of a laser or white-light, computer-generated projections to perform surface measurements of three dimensional objects. n. 1 The use of a technique in the measurement and profiling of an object. 2 The methodology of performing eddy current profiling of tubing. 3 The technique in which a diamond stylus, in contact with a sample, measures surface variations as a function of position. 4 The use of a laser or white-light, computer-generated projections to perform surface measurements of three dimensional objects.
