An automatic alignment system using differential phase‑sensing was experimentally demonstrated on the 10‑m prototype laser interferometric gravitational‑wave detector in Glasgow. The system controls the orientations of two mirrors in a 10‑m suspended Fabry–Perot cavity relative to the input laser beam. Test results show the system performs as intended, with performance discussed in the paper.
An automatic alignment system, based on a differential phase-sensing technique described in a companion paper [Appl. Opt. 33, 0000, (1994)], has been experimentally demonstrated on the 10-m prototype laser interferometric gravitational wave detector in Glasgow. The alignment system developed was used to control the orientations of two mirrors in a 10-m-longsuspended Fabry–Perot cavity with respect to the direction defined by the input laser beam. The results of the test and a discussion of the performance of the system are given.
