Paper Abstract

The objective of this report is the presentation of the experience gained in the experimental determination of the spatial correlations in a turbulent velocity field by means of an especially designed Laser-Doppler (LDV) holographic optics. The determination of the spatial velocity correlations requires the generation of two closely spaced LDV measuring volumes at specified positions. In conventional LDV optics this spacing is limited by the size of the optical components. The holographic optical elements (HOE) used in this work facilitate the positioning of the measuring volume at a spacing of 200 micrometers or better. Basic design considerations, the manufacturing of the holographic optics and the data acquisition are discussed.
