Abstract

Wind generates vibrations in towers and in telescopes placed in the open air. Interferometers for measuring these vibrations were developed. Applications to scale models of a telescope led to improvements of the telescope design. An optoelectronic system using three photocells for scanning the interferometer fringes allows the application of an inexpensive laser with several longitudinal modes as a light source for the interferometers.
