WebApr 2, 2024 · Figure 1: Michelson Interferometer. In Michelson interferometer, a beam splitter and two mirrors are used, in which one mirror is fixed and the other is movable (see Figure 1). When a light ray from the source falls on the beam splitter, it gets separated into two rays at 90°. One ray is projected towards the mirror m 1 and other is reflected ... WebFeb 11, 2016 · A key task is "locking" the interferometers, which means stabilising the separations between the mirrors so that the laser light resonates between the mirror surfaces as it was designed to do.
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. WebIt builds up the laser light within the interferometer, which increases LIGO's sensitivity (more photons also makes LIGO more sensitive) 2. It increases the effective distance traveled by each laser from 4km to 1200km. (The …
