The theory of the mirage is reviewed at several levels of complexity, in order to show that the phenomenon can usefully be discussed in teaching. In addition, an experimental device has been set up to obtain the mirage in the laboratory under controlled conditions, with the possibility of observing the finer details discussed in the theory. 
The double superior mirage in a specialized school
It was revealed that an explanation of the formation process of a double superior mirage plays a key role in the adoption of knowledge on reflection and refraction of light, as well as its practical skills in a specialized school.
Mirages in a Bottle.
A simple experiment is presented to visualize inferior and superior mirages in the laboratory. A quantitative analysis is done using ray tracing with both photographic and computational techniques.
Mirage in a box: a classroom activity on the refractive index gradient
The presentation will illustrate how to realize, in a transparent tank, a stable refractive index gradient by using sucrose solutions and a gelling agent. The apparatus will be used in a classroom
Road surface mirage: A bunch of hot air?
The inferior mirage from road surfaces is a common phenomenon, which can be easily seen in everyday life. It has been recognized in the literature as a light refraction phenomenon due to the
A note on ray tracing mirages (comments and author's reply)
The author comments on an article by M. Berger et al. which describes a model for forming a mirage, and points out that the primary bending agent in mirage formation is total reflection, not refraction, which indicates that a purely reflective model, without refraction might well be sufficient.
Real-Time Simulation of Dynamic Mirage Scenes
By incorporating GPU acceleration into the rendering process, different types of dynamic mirages under different conditions can be realistically rendered in real time, demonstrating the formation, change, and disappear of mirages.
Temperature profile and double images in the inferior mirage
Desert mirages were simulated in the laboratory by heating a flat surface of sand. This showed that a boundary layer of air, of only a few millimeters immediately covering a heated surface has nearly
Ray tracing mirages
Ray-tracing methods are extended to include the mirage effect by simulating atmospheric variations by distinguished air layers, each layer being assigned a refractive index which causes a penetrating light ray to bend in accordance with Snell's law of refraction.
Physical and unphysical phases of uniformly accelerated particles
The motion of an electron in a uniform electric field, as in free fall, is characterized by the existence of pairs of trajectories that rejoin on the same final point. The corresponding interference
Numerical reproduction and explanation of road surface mirages under grazing-angle scattering.
It is suggested that the light-enhancing effect of the rough surface under grazing-angle scattering is not proper to be termed as "off-specular reflection," since it has nothing to do with the "specular" direction with respect to the incident direction.
