Aberration influenced generation of rotating two-lobe light fields

Abstract

Abstract. The influence of aberrations on light fields with a rotating intensity distribution is considered. Light fields were generated with the phase masks developed using the theory of spiral beam optics. The effects of basic aberrations, such as spherical aberration, astigmatism and coma are studied. The experimental implementation of the fields was achieved with the assistance of a liquid crystal spatial light modulator HOLOEYE HEO-1080P, operating in reflection mode. The results of mathematical modelling and experiments have been qualitatively compared.

3D imaging of semiconductor colloid nanocrystals: on the way to nanodiagnostics of track membranes

“…In present paper the experimental test of original calculated phase transformation elements (masks), that allow the transformation of point spread function in double helix scheme, was conducted [9]. Also it was shown, that the accuracy of reconstruction of coordinates of quantum dots (CdSe/ZnS), inserted in liquid solution in polycarbonate track membranes, reaches several dozens of nanometers.…”
