A dynamic interferometric system which can sequentially measure changes in an object at short intervals has been constructed. Holograms are recorded in a BSO crystal and the phase conjugated wave fronts are generated sequentially, so that only interferograms of changes in the adjoining intervals are obtained. From the detected interferogram the amount of change is calculated for the desired parameter and it is displayed on a CRT in 3-D. The construction of the device and some measurement results are given.
