NASA's Dittoscope is a Precursory Holographic Telescope to Study Cosmic Hologram Phenomena


Holographic microscopy techniques can enable future telescopes to study cosmic holograms in outer space.  Thomas Ditto writes "The laws of physics will allow scaling up hologram production to hundreds of meters in length, to build a newly designed double diffraction telescope. Variable pitch gratings of the type that focus are typified by holograms that have a spherical wave as their object and a plane wave as their reference. This creates a variable pitch that is chirped in wavelength according to a hyperbolic function, by using grazing incidence equivalent for holographic microscopy.

Thomas Ditto writes "We introduce double diffraction in an embodiment with a new type of primary objective grating (POG) as an alternative to telescope mirrors. The acquisition of spectra can reach into the millions of objects per observation cycle." "Scaling up would be a sensible goal, since more spectrograms can be taken with greater resolving power." "The holographic primary is appropriate for a static pose of the POG. With plane gratings motion along the axis of diffraction is possible even over a kilometer scale POG, using a venetian blind architecture. Segments can be tilted gradually to change incidence angles over small excursions. Such precise movement is possible using piezo pistons. Objects (galaxies) could be tracked for the period the angular excursion would allow, that might be tens of seconds. In the other dimension, any POG can be moved off its strict east/west line."
