摘要
Interferometric system with variable optics for non-coherent source of radiation and method of interferometric system alignment The invention relates to the interferometric system for creation of hologram with spatial carrier frequency comprising a source of radiation (1) with low coherence, behind which a field plane (2) optically conjugated with an output image plane (10) is arranged, a beam splitter (4) for splitting the beam of radiation into two separate branches of interferometer, an object branch with plurality of optical elements, a reference branch with plurality of optical elements, a diffraction grating (7), an extender (12), a transmission system of reflectors and a detector arranged in the output image plane (10), wherein the plurality of optical elements in the object branch includes a objective lens (5.12), wherein the objective lens used in the reference branch is not identical with the one used in the object branch, which means a significant financial saving. The system comprises object and reference input imaging systems (5.1) and (5.2) and object and reference output imaging systems (8.1) and (8.2) wherein one of them includes an optical element with variable focal length.
