This presentation provides information on experimental generation and application of the superposition of higher-order Bessel beams. The superposition of zero order Bessel beams can be used to measure the radius of curvature of a reflecting surface.
This approach is based on the fact that the intensity distribution of the superimposed Bessel beams is a sensitive function of the relative phases between the constituting beams.
