摘要：

A digitial double-pulsed holographic system will be described. Two separate holograms of an object under test are recorded within a few microseconds using a CCD-camera and stored in a frame grabber. Different recording arrangements for Fresnel hologram, quasi-Fourier- and image-plane hologram are discussed and compared. The holograms are reconstructed digitally using a computer. The phases of the two reconstructed wave fields are calculated from the complex amplitudes. The deformation information is obtained from the phase difference. In the case of the image-plane hologram the deformation can be obtained by using a sinusoid-fitting method without reconstruction of the wavefront Experimental results are presented.
