(A and B) Examples of numerically calculated escaped n(r) for $R=10\hspace{0.5em}\mu \text{m},\hspace{0.5em}r=1\hspace{0.5em}\mu \text{m},\hspace{0.17em}\alpha =10$. (C, D, and G) Experimental 3PEF-PM textures obtained by superimposing images of g = 3–5 drops for linear polarizations of probing light at $0°$(red), $45°$(green), $90°$(blue), and $135°$(pink). (E and F) Experimental POM images of a g = 5 drop obtained (E) without and (F) with an inserted 530-nm phase retardation plate having a slow axis along the blue double arrow.
