Paper Abstract

A simple technique of obtaining light spiral (helium) filters in UV exposed photoresist layers consisting in a combined use of binary masks and revolution of the photosensitive layers during exposition is presented. The filters investigated experimentally are inspected by observing intensity distribution in a laser beam reflected from the sample. The filter giving the angular phase shift variation which is close to that needed for the generation of the first order Bessel beam is realized.
