| 摘要 |
The invention relates to an attachment for a light-emitting video projector, whose beam incorporates a respective left and right stereoscopic field arranged spatially next to one another. The projector is used to project 3-D stereoscopic images on a projection surface, on which the projection planes are retained to a great extent, said images being viewed with a pair of polarisation glasses. The aim of the invention is to develop an attachment of this type, which overcomes the disadvantages of prior art and which is used to create stereoscopic images on a projection surface, on which the polarisation planes are retained to a great extent, said images being viewed with a pair of simple polarisation glasses. To achieve this, the attachment in one embodiment consists of at least two rotative mirrors (2), in addition to a filter comprising a retardation film (3) for rotating the polarisation direction of the light through 90 DEG and the retardation filter (3) and the two mirrors (2) are aligned in relation to one another in such a way, that only the polarisation direction of the light beam of one of the two stereoscopic fields is rotated by the retardation filter (3) and both stereoscopic fields are projected in a superimposed manner on the projection surface (5). |
