摘要：

Electronic speckle pattern interferometry has been used to measure the vibrations and deformations of objects located far from the optical head. Vibration recordings were made for a total path-length difference of up to 200 m with the object outdoors in bright sunshine. This limit was determined by practical considerations. For deformation recordings, turbulence and mechanical instabilities create a problem, and a more realistic limit is a path-length difference of about 50 m under stable, indoor conditions.
