Proposal of new optic elements G. Chadzitaskos Department of Physics, FNSPE, Czech Technical University in Prague Stará Lesná 2012
Overview • Two diffraction grating • Parabolic strip telescope • Objective for X ray microscopy • CNOT on polarizated states of light • Objective for X ray telescope
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.
Maximacase 1 : case 2:
Exploitation • Measurement of coincident part of light • Measurement of cross sections of interaction light and electrons (two slit experiment)
CNOT ON POLARIZATED STATES OF COHERENT LIGHT Optical activity of molecules with magnetic dipole
Exploitation • Quantum optics
PARABOLIC STRIP TELESCOPEPrinciple Rotation around y axis and Radon inverse transform
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, optimalization Uint8 and image
Images of artificial star constellation Original images at 0, 45, 90, and 135 degree After MATLAB calculation
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
