Two diffraction systém(Wikipedia)
.
Two diffraction system
The light from monochromatic light source 1 is divided into two channels 3, by a 1:1 beam splitter 2, and is brought into the two-diffraction gratings 5. Two-diffraction grating generally consists of a large number of equally spaced slits, which allows connection of one channel with odd slits and the other channel with even slits 4. Then spots 7 – interference maxima – appear on the screen 6.

PARABOLIC STRIP TELESCOPEPrinciple
Rotation around y axis and Radon inverse transform
Used experimental plexiglass telescope objectives
Artifitial constelations
Image procesing
From camera RGB uint8 Select central part, make
matrices 600 x 600x 3 and rotate, single precision
12th root of real matrices Point multiplication of 0
and 90 degree matrices Point multiplication,

Advantages \• good angular resolution• low expenses• simple technological development• simple exploitation of adaptive optics• possibility to install a net of large telescopes over the Earth• lower weight for use on satellites
Proposal: Over Earth net of telescopes (30 degrees)
• high mounting not necessary• low wind influence• low gravitational influence
Objective for X ray microscopy
Fresnel zone plates, polycapillar optics, Goebel mirrors, biconcave refractive optics.
New: Spatial grating – Bragg’s and interference conditions

Děkuji za pozornost
Pro destičku germaniového monokrystalu a teploty mezi 250 a 1000 K je pro vlnovou délku 0.5 nm hodnota například pro xmin = 10 cm bude xmax = 10,8 cm.
