Abstract
We present a system for electronic speckle pattern interferometry (ESPI) us ing fibres and spatial phase shifting with active phase stabilisation. The control loop for the synthetic heterodyne phase stabilisation system is inc luded in the measuring set-up. No additional optical components are require d and the phase is stabilised at one image point of the field of measuremen t. (C) 2000 Elsevier Science B.V. All rights reserved.
