Paper Abstract

The analog reconstruction of a wave front and its application in comparative measurement is well known from comparative holography. Thanks to the rapid development of high quality spatial light modulators (SLM), different methods applying the analog reconstruction of digital holograms has been developed in digital holography too. In these methods the recorded wave fronts of an object are generated by the spatial modulator. The SLM is also capable to generate computer calculated wave fronts (not belonging to an existing object), and multiple such projections can be performed during the measurement time. Using this feature an effective adaptive measuring system can be built. The application of such wave front projections is also possible in TV holography. The wave front projection can be virtually too, when the wave front exists only in the computer memory. Methods both for digital holography and TV holography are developed too.
