Abstract
An automatic alignment system, based on a differential phase-sensing t echnique described in a companion paper [Appl. Opt. 33, 0000, (1994)], has been experimentally demonstrated on the 10-m prototype laser inte rferometric gravitational wave detector in Glasgow. The alignment syst em developed was used to control the orientations of two mirrors in a 10-m-long suspended Fabry-Perot cavity with respect to the direction d efined by the input laser beam. The results of the test and a discussi on of the performance of the system are given.
