Abstract: A system is proposed for excitation of luminescence with the help of diffraction axicons with a ring aperture to detect luminescent images. The excitation beams are visualised using LiF crystal radiophotoluminophores. It is shown experimentally that spatially truncated Bessel beams formed in this case provide the local excitation of luminescence in the region of diameter 1.6μm and length 3 mm.
