Embodiment 1

[0046] Example 1: Beam scanning through two rotating optical discs

[0047] The device given in Example 1 (Figure 2) includes two rotating optical discs, such as rotating optical discs (26, 27), which according to the specific arrangement includes a large number of mirrors and / or filters and / or cavities In the chamber (28), the light beam (30) scans the display area (29) through the first vertical movement and the second horizontal movement. The rotation of two rotating optical discs with continuous beams (30) can determine their characteristics on the display area (29) (Figure 3). In addition to spatial movement, mirrors and / or filters can perform spectral corrections, for example, filtering during beam reflection, beams with a spectral shape (30), such as (31), after being changed by the first reflection Give e.g. (32) and give e.g. (33) after the second reflection.

[0048] For example, on one of the features (34) and (35), due to the two mirrors and / or filters (37) and (38) th...

Embodiment 2

[0051] Example 2: Multi-beam scanner

[0052] The optical multi-beam digital video projection engine device (Figure 8) is used to generate a series of video images through the lithographic structure, that is, multi-beam digital vector processing. This processing optimizes the use of the engine by arbitrarily scanning the screen by any set of light beams to synthesize and / or generate images. This group of beams, for example, the laser is processed as a series of vectors that pass through a large number of interfaces and / or devices, for example, a plane simulated by a static or dynamic transfer function. From the perspective of space, frequency, and time, the transfer function can be Define, for example, different beams, vectors, and coupling elements at the start and end points of each interface.

[0088] Depending on the implementation and use variants, multi-beam digital vector processing allows driving, for example, an optical digital transmission device (Figure 19), which consists of:

[0089] --- A large number of rotating optical discs, such as (91), (92), (93), (94), and (95);

[0090] --- A large number of delay lines, such as (96);

[0091] ---At the input end, there are a large number of optical matrix heads, such as crown components, pyramids (97) and / or stacked mirrors and / or filters (98);

[0092] --- At the output end, there are a large number of optical matrix heads, for example, crown components, pyramids (99) and / or stacked mirrors and / or filters 100);

[0093] The optical digital transmission device (Figure 19) allows cross connection and / or routing and / or routing in optical telecommunication networks by rotating optical discs, such as (91), (92), (93), (94) and (95) Or conversion, ...

Abstract

The invention concerns an Electromagnetic Multibeam Synchronous Digital Vector Processing device (figure1) which represents, controls and determines the shape, the position, the path, and all of the characteristics of electromagnetic beams scanned in any optomechanical or optoelectronic device, whether plane-, disk-, cylinder-, sphere-, surface-, or volume-based, active and / or passive, static and / or dynamic, on any surface or in any volume. The device is formalized by space-time (12b) and vector (12a) timing diagrams indicating space-time anchor points (14), (15), (16), (17), (18) and (19), and is resident in a programmable logic component, in the form of a multi-frame time synchronization structure which has the role of managing the optical paths (1) taken based on the free space propagation of the various beams, for example Gaussian beams. The device is incorporated into a Digital Video Projection Engine, an Electromagnetic Multibeam Scanning Engine, an Optical Digital Transmission system with Rotating Optical Disks or a series of matrix diagrams, for example dynamic micro-mirrors arranged in a specific geometry, thus allowing the use of same in various fields of application, for example the audio-visual, telecommunications, biomedical, radar detection and 2D and / or 2D digitization fields.

Description

Technical field [0001] The present invention relates to a device for generating multi-beam digital vector processing. The device can be implemented by an optical mechanical system, such as a digital video projection engine, an electromagnetic multi-beam scanning engine, and an optical digital transmission device.
