How does a laser interferometer work

WebThe interferometer is the heart of FTIR and consists of a beamsplitter, a stationary mirror, a moving mirror, and a timing laser (box in figure 4). The beamsplitter splits the light from a source into two paths with half the light going to a stationary mirror and the other half going to a moving mirror. WebBasically, an interferometer splits a beam of light (usually a laser) into two components: a reference beam and a sensing beam. The reference beam will travel unaltered through an …
