interferensmätning
Interferensmätning is a measurement technique that utilizes the phenomenon of optical interference to determine physical quantities. This technique relies on the superposition of two or more light waves, resulting in a pattern of constructive and destructive interference. The observed interference pattern is highly sensitive to variations in the optical path length between the interfering waves. By analyzing these patterns, precise measurements can be made of parameters such as distance, refractive index, surface irregularities, and the thickness of thin films.
The core principle of interferensmätning involves splitting a coherent light source, typically a laser, into two
The sensitivity of interferensmätning is exceptionally high, often capable of detecting changes in optical path length
