Abstract

The design and realization of a novel targeting method based on non-diffracting interference technique are proposed in this paper. An axicon lens can be used to produce non-diffracting beam, which is a conical refracting surface, and gives rise to a conically converging wave front. This produces a line focus with an extended Rayleigh range, determined by the radius of the input beam and the base angle of the axicon. Edge and feature points are basic low level primitives for image processing. The justification is that such points convey a lot of structural information about the surfaces of the objects captured in the imaging process. For this reason, edge and feature detection are two most common operations in image analysis. The SUSAN approach is in this paper utilized in edge and feature detection and smoothing.
