Abstract

The invention relates to a technique for receiving, transmitting and processing three-dimensional optical information and can be used to create surround television systems, three-dimensional indicators, in robotics for technical vision systems, for volumetric visualization of objects located inside closed volumes and not available for direct observation, as well as in optical information processing devices. The aim of the invention is to increase the informativeness of image transmission by reducing the loss of information on the spatial, spectral and temporal coordinates of the optical signal. The basic principle underlying the invention is the sequence of presenting information about the spatial characteristics of objects in the form of a set of intensity distributions of incident radiation on a given surface depending on the angle of incidence for a set of points on a given surface. To implement this principle, after dividing the light beam from an object into N beams in space, the optical conversion of each IJ beam into the reading plane, reading it, transferring its intensity to the reproduction plane, reproducing and transforming into image space through the IJ aperture, thereby reducing the bandwidth of the communication channel. To implement the radiation method, they are successively passed through the IJ cell of the controlled transport 5, assembled with the lens 6 at the end of the fiber optic bundle 1, and from the output end of the lens 9 are converted through the IJ cell transparency 10 into the image space. To synchronize the operation of the banners, two synchro generators 7 and 11 are used with the channel 3 for transmitting the clock signals. To invert the three-dimensional image, the reading plane is aligned with the reproduction plane. 2 p.4 hp f-ly, 5 ill.

image reduction due to the loss of information on the spatial, spectral and temporal coordinates of the optical signal. The basic principle underlying the invention is the sequence of presenting information about the spatial characteristics of objects as a set of intensity distributions of incident radiation on a given surface depending on the angle of incidence for a set of points on a given surface. The screeching and transformation into the image space through the ij-th diaphragm is carried out sequentially, due to which bandwidth limitations are removed.

The input and output converters comprise an image luminance amplifier 8 of an input converter, a luminance amplifier 12, or a diffusing element of the output converter.

Element i (Fig. 1) from the set of receiving elements k receives beams of rays 1i, 2i, 3i, which characterize the angular intensity distribution for the i-element when exposed to radiation tpexMepHoro of a three-point object formed by a set of points 1-3. The set of receiving elements 4 is in this example the set of elements of the transplanted transparency, successively set to the transmission mode of the radiation. After passing the lens 5, the beams of the b, 2i, 3i beams form on the given surface 6 the coordinate distribution of the illuminance Ej (x) corresponding to the angular distribution of intensity for the i-ro element in the plane of the transparency. Similarly, the beams of the beams j, 2j, 3j form on the given surface 6 is the illumination distribution Ey (x) corresponding to the angular distribution of intensity for the j-ro element in the plane of the transparency 4.

After transmitting the obtained illuminance distributions in the direction indicated by arrow 7 to the radiating surface 8 and the inclusion of the corresponding elements of the transparency 10, a three-dimensional image of a three-dimensional object formed by a set of points 1, 2, 3 is obtained. For the geometric construction of the image, only two distributions are sufficient: i.-ro and j-ro, which is reflected in FIG. 1, intermediate points: 1

pseudoscopic in relation to the object I, 2, 3, i.e. its depth is inverted (point 3 with respect to points 1 and 2 of the image and point 3 with respect to points 1 and 2 of the object have the opposite arrangement). According to the proposed method, an inverse or reproducible image is inverted to obtain a three-dimensional image orthoscopic with respect to the readable one.

The property of inverting the depth of the image by the proposed method of reading, transmitting and reproducing three-dimensional optical information can be used directly to solve the problem of inversion, which can be illustrated in Fig. 1 by combining planes 6 and 8.

The change in the direction of the beams in accordance with Fig. 1, incident and emanating from such a plane, can be achieved in the simplest case by placing a scattering element in this plane. The double conversion of the volumetric image according to the proposed method allows to obtain a volumetric image that is orthoscopic readable.

The device (Fig.) Works as follows.

The radiation scattered and emitted by the object 13 falls on the readout unit 2, in the output plane of which (at the input end of the light guide wiring harness 1) intensity distributions are successively formed corresponding to the included elements of the banner 6. On-off elements of the banner are determined by control signals coming from the sync generator 7. Objective 5 serves to match the dimensions of the controlled transparency with the input end of the fiber bundle 1. On the fiber bundle 1, the generated distributions Illumination is transmitted to the playback plane of the playback unit. At the same time, information on the number of the transmitted intensity distribution is transmitted via the sync signal transmission channel 3 (the number of the included element of the controlled converter generates a turn-on signal similar to electri: i -., "- t; -; - 1: 0 l me.
