Abstract

We propose a novel approach to calculating light field distributions within geometric optics. A new integral operator to calculate the intensity distribution within geometric optics is described. Using the proposed technique, intensity distributions from earlier studied beams are derived. Singular points of the distributions are found and near-caustic intensity patterns are derived. Based on the proposed approach, caustics generated by radially symmetric harmonic diffractive elements are calculated.
