Some Considerations On The Quantitative Interpretation Of Holographic Interferograms

Abstract

In a holographic recording and reconstruction configuration, in which the object illumination source and the center of projection of the observation system seem to coincide, the accurate measurement of the sensitivity vectors is simplified considerably. Therefore, quantitative interpretations of the holographic interferograms are obtained with relatively small effort. If a dual reference beam double-exposure set-up is used, the sense of displacement components can be found and extremes in the scalar product of displacement vector and sensitivity vector can be detected when a relative phase shift is introduced in the reconstruction beams.© (1978) COPYRIGHT SPIE--The International Society for Optical Engineering.
