Light scattered from spheroidal drops produces a variety of complicated diffraction patterns which are examples of optical catastrophes. These patterns decorate caustics in the outgoing rays which have been refracted by (and internally reflected from) the drop’s surface. Near the rainbow scattering angle, hyperbolic umbilic, cusp, and other catastrophes have been observed with laser and white light illumination. Lips caustics in the backscattering pattern have also been obseved. Calculations of caustic parameters (from generalized ray tracing) and wavefields are summarized.
