The invention relates to a device (FIG. 14) making it possible to generate a group of light beams with statically or dynamically controlled pointing adjustment, e.g. with the aid of an optical matrix head feeding the last stage of an item of multibeam digital projection video equipment, comprising a certain number of rotary optical disks. The device comprises a certain number of elements/devices for static adjustments, e.g. of screw plus spring type, or dynamic adjustments, e.g. of micro jack and/or piezo-electric type, carrying out dynamic trim control with the aid of a device, e.g. of pyramidal, conical or other shape, within an optical matrix head. A digital control providing feedback control for the position and lighting of the sources thus makes it possible to create a succession of coloured pixels at the output of the device. According to the desired configurations, several sources may be associated, e.g. within an optical matrix head, to create a matrix of coloured pixels. Depending on the architecture of the video projector used, the optical matrix head devices and integrated optical source modules block are supplemented with an optical deviation periscope. The device is intended for the very top of the range in Digital Cinema and then subsequently for “Home Cinema”.
A multi-beam digital projection video motor device characterized by a certain number of superimposed optical rotating discs, comprising themselves a determined mirrors and/or filters layout, causing the deviation of a parallel incident beams set from, for example, an emission block constituted of a certain number of sources modules and/or a certain number of matrix heads, comprising a certain number of optical sources modules, coloured beams generators or deflection pyramids, said deflection being oriented for example vertically by the first optical rotating disc and horizontally by the second, and comprising in addition a deflection optical periscope device with two mirrors and/or filters constituting a reflective prism, or, according to the configurations, a certain number of mirrors and/or filters, for example (71) and (72), allowing to attack the first disc with a predetermined angle introducing a low obstruction.
A device according to claim 2 characterized by the pyramid-shaped element of the optical matrix head for multi-beam digital video projector which is protected by transparent or perforated walls, which allow the passage of beams from the source modules towards the device mirrors or filters, where a certain number of protection devices allows them to be stacked together to compose the pyramids arborescence according to claim 9 with or without the help of an intermediate plate.
