Refraction is surely one way to do it. Keep in mind that most if not
all types of mirages are caused by the variable ior of hot vs. cold
air, and in POV there's no variable ior. One can however use a distant
transparent plane with refraction and a varying normal to achieve if
not a mirage then at least a heat wave effect. Another idea is to use
the camera ray perturbation feature in POV. One way or the other
you'll have to fake it.
