Obtaining and processing schlieren images of gasdynamic processes by using automatic digital systems

The techniques and instruments for visualization and recording of gasdynamic flow schlieren patterns by using image recording and processing digital system are presented. The results of gasdynamic facility tests are shown. The efficiency of developed techniques and means is demonstrated to rise sufficiently basic visualization parameters (responcitivity, dynamic range, and minimal measured performances) as well as to increase volume of received results information.
