Optical systems that generate special catoptric effects composed of reflector prisms - formed with flat mirrors and flat semi-reflector glasses - arranged in orthogonal combinations, which produce such effects by controlling the path of the light from the observer object and from any object of interest. The purpose of the Catoptric Module is to generate non-ordinary virtual images of the subject or object, where the image plane is parallel to the observation plane, the conjugated element is centred on the optical axis and the parasite virtual images also produced by the optical system and that do not respond to the purpose of each specific catoptric effect are eliminated from the field of vision of the viewer.It is applicable in entertainment industries, in product or service presentation and exhibition systems, real estate, decorative elements, toys, as well as in the domain of psychotherapy and teaching of physical disciplines.
