ABSTRACT:
An apparatus and method are provided for producing images having a depth or relief component (e.g., appearing three-dimensional) from single perspective projection masks. The three-dimensional relief images are generated from two-dimensional images utilizing a simplified electromechanical device. In this regard, an oscillating light redirecting system is used to synthesize a third dimension onto a two-dimensional image resulting from projecting light through a single perspective projection mask. The light redirecting system controllably deflects the light projecting through the projection mask about two axes prior to the resulting image being projected on a surface. When projected onto a surface, the resulting image is controllably spread over two axes such that it appears to be a three-dimensional relief image. In a further embodiment, color filtering is utilized in order to produce color three-dimensional relief images.
