Abstract : The laser-differential interferometer described in ISL-T 21/70 and ISL-14/71 underwent further development. It now constitutes a versatile measurement instrument able to be utilized advantageously in the following fields: flow calibration in gas-dynamic facilities, compressible gas dynamics, in particular various types of boundary layers, gas kinetics or chemical kinetics, turbulence investigations, acoustics. The optical arrangements suitable for the respective problems - for the most part already tested - are systematically compiled, and the possibilities of the techniques are demonstrated in a wide variety of examples.
