Method and device for observing moiré patterns of surfaces under investigation in conjunction with the application of the projection moiré method with phase shifts

摘要

Dynamic and brief measurement of surfaces and surface variations by means of the projection moiré method in combination with phase shifts. The invention relates to the recording of surfaces and their deformation in the direction of observation. It relates to a method with exemplary embodiments of the device for the simultaneous pulling- in of the individual images which are required for the application of the phase shift method when the latter is used in the case of the projection moiré method. The brief observation and recording of moving surfaces is rendered possible by the advance from serial to parallel pulling-in of the shifted patterns. The temporal resolution is now a function only of the storage/exposure of a photograph.
