Multi-beam digital projection VIDEOMOTOR having a static or dynamic correction rejects the periscope or without

摘要

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 piezoelectric 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”.
