Measuring with Light
Long applied to optical shop testing, interferometry is now used to measure many different types of parts in a variety of applications, such as optical system performance, surface roughness, surface form, and  displacement of moving surfaces. An interferometer is an instrument which generates and compares the differences between two lightwaves which are reflected off two different surfaces. In practice, interferometers are used to measure the quality and performance of optical...
