MULTILENS SPHERICAL PROJECTOR Russian patent published in 2023 - IPC G03B21/14 

FIELD: imaging.

SUBSTANCE: invention relates to projection-based means of reproducing images indoors. Multilens spherical projector comprises a spherical body wherein at least four objectives are mounted in the horizontal plane of the spherical body on the four sides at an angular distance of no more than 90° from each other; at least one of the objectives is mounted in the body on the vertical axis of symmetry on the side opposite to the attachment assembly; a light source is mounted inside the spherical body in the geometric centre thereof, four optical paths and one optical path perpendicular to said paths are mounted therefrom in a horizontal plane. A condenser is mounted inside each path, a TFT matrix is mounted behind the condenser, and an objective is mounted behind the TFT matrix. The TFT matrix and the objected are linked with a processor used to manage and match images. The processor is linked with a data loading unit located under the processor and connected to the switching inputs.

EFFECT: reduction in the weight and size characteristics of the projection equipment with a simultaneous improvement in the quality of the projected images.
