This invention relates to optical-electronic technology and can be used for building 3-dimensional displays for computers, television (TV) receivers and other devices, as well as for building systems for volumetric television. The technical result is an increase in the number of aspect angles with relatively simple construction and the use of presently available components. The equipment generates a 3-dimensional representation and contains a display component for 2-dimensional representation with digital inputs and a first 2-dimensional matrix of converging micro-lenses, in which each micro-lens is optically joined to the corresponding region of the display surface of the component for display of 2-dimensional representations. The equipment is equipped with second and third 2-dimensional matrices of micro-lenses, tightly connected to each other and coaxially placed and optically joined to the micro-lenses of the first matrix, forming in conjunction with the first matrix a matrix of scanning elements for sequential projection of 2-dimensional representations in the plane of their aspect angles, an adjustment mechanism of the matrices of micro-lenses, a positional sensor for adjustment of the micro-lenses and a controller connected to the adjustment mechanism through the digital input of the controller, providing the ability for synchronization of the frames of the representation of each 2-dimensional representation with the corresponding position of the matrix of micro-lenses, while the second matrix is arranged in the foreground focal plane of the third matrix, mixed with the background focal plane of the first matrix, and the first matrix or the combined second and third matrices can be adjusted in the plane in which they are installed, and moreover for the first, second and third matrices, the digital input of the display component is connected to the module of buffered memory, whose synchronization input is connected to the output of the controller. The described equipment can be used with a stereoscopic television system.
