Abstract

The great interest in PIV measurements in many different fields of research requires also a flexible image shifting system which can be applied to a variety of experimental situations. Image shifting is primarily known as a method for eliminating the ambiguity of the direction of the velocity verctor within PIV recordings. Further capabilities of the image shifting technique which increase the general applicability of the PIV-method will be described. The advantages of the proposed proceeding is demonstrated by referring to a variety of wind tunnel-experiments carried out by us.
