Embodiment Construction

[0029] With reference to the accompanying drawings, the optical multi-beam scanning digital video projection device (Fig. 1) can project to any surface or in any volume within the solid angle of 0 to 360 °, such as 180 °, 270 ° or 360 °, and / or perform 2D or 3D recording / digitization, the device includes a certain number of light sources (1), arranged in a certain way on a certain number of levels or coronal volumes, such as (2), (3), (4), (5 ) and (6). The light sources used, e.g. weak / medium / high power lasers can be integrated e.g. into optical source modules, into color pixel generators, a certain number of optical matrix heads, e.g. crowns / pyramids of mirrors / filters type or paving layer. A collimated or low divergence beam, such as from a light source (7) is angled towards the addressing periscope (8). By means of a certain number of mirrors / filters arranged in a particular way on, for example, an addressing pyramid (8) and / or a cone, the addressing periscope sends a li...

Abstract

The invention relates to an optical digital video projection device for multi beam projection onto any surface or into any volume in 2D or 3D, within a solid angle from 0 DEG to 360 DEG. The device can also be used in digitiser and / or radar function for the recording / digitisation of spatial and frequency information. The processing of electromagnetic radiation, for example, visible, infrared ultraviolet, microwave radiation in time, space and frequency either passively or actively for example, by means of mirror / filter windows permits a filter function specific to the target applications. The source uses a light source comprising, for example, a number of weak / medium / high power lasers coupled to a number of optical sources, optical source modules, coloured beam generators or optical matrix heads. The digitisation function uses, for example, a number of photodiode capture devices, charge coupled devices (CCD), etc. The function for digitisation / optical radar in 2D or 3D using light beams permits use in different types of application, in telecommunications, for road maritime, aerial or space navigation.

Description

technical field [0001] The present invention relates to a device for electromagnetic multi-beam digital video projection, which can be used in 0 to 360°, such as 180°, 270° or 360°, by using a certain number of low-power / medium-power / high-power lasers as light sources Multi-beam digital video projection onto any 2D or 3D surface or into any space within a range of solid angles, such as visible light, infrared, ultraviolet or microwave optics. The application of a set of sensors coupled to a light source allows the device to be used as a 2D or 3D digitizer and / or radar within a solid angle range of 0 to 360°, eg 180°, 270° or 360°. Fields of application of the invention may be: digital video projection onto surfaces or into spaces, telecommunication equipment for road, sea, air or space navigation. Background technique [0002] 360° screen display is often performed through various multi-screen assembly methods. A strip-shaped screen layout composed of multiple screens wind...
