Method and system for multizone imaging of objects

摘要

The method for multizone imaging of objects consists in converting the object image into an image of the spatial frequency spectrum of the object, in which the information on the spatial object structure is contained. In this case, a selection is made in this spectrum of at least one zone whose radiative flux is integrated in real time to generate video signals which correspond to the relevant object image. In the multizone system, a space/time modulator (14) and an optical element (15) for converting the object image into an image of the spatial frequency spectrum are arranged in series upstream of the device (16) for the purpose of splitting up the spectrum. <IMAGE>
