The accuracy of all the analytical results is verified by Monte Carlo simulation.Starting from a peculiar image observed below a bubble that is floating at a water-air interface, this paper analyzes several optical properties of these special types of refracting objects (termed bubble axicons). Using mainly geometrical optics, their relation to common axicons, the shadow-sausage effect, and elementary optical catastrophes (caustics) are discussed.While using digital halftoning to achieve multi-tones in a 1 bit electr
