Abstract:
The exemplary embodiments disclosed herein provide a light diffraction device positioned adjacent to a wall and comprising a laser and a diffractive imaging element. The diffractive imaging film having an image and positioned relative to the laser so as to create a projection of the image upon the wall. The diffractive film can also contain a series of images where the film is moved relative to the laser in order to create an animation effect upon the wall. In some embodiments, a distortion reflector may be positioned to accept the laser light exiting the diffractive imaging film and to distort the laser light to produce a desired image upon the wall. In some embodiments, additional reflectors may be used and in some further embodiments a distortion lens may be used.
