Abstract: FIELD: image processing. 
     SUBSTANCE: invention relates to methods and devices for capturing and processing images, and in particular to image restoration based on back ray tracing technology. The result is achieved by installing the underground camera as a point of emission of the light source and emitting rays into the underground area displayed by the camera; record all points of intersection of all rays and underground objects and calculate one point of intersection closest to the viewpoint at the intersection points; calculating the direction of the rays newly generated after the rays are reflected and refracted by the objects at the intersection point position; accordingly, the rays generated again are traced; recording the beams emitted onto the viewing plane after the strong light source emitted from the camera position is reflected or refracted three times, and calculating the light intensity of the beams; converting the light intensity into a pixel value by means of a photosensitive member with a semiconductor camera light detector; and eliminating the pixel value of the strong light emitted from the camera from the image ultimately shown on the viewing plane to obtain the image after removing the influence of the strong light source. Thus, it is possible to effectively eliminate the influence of the strong light source, restore the underground image, and ensure the smooth operation of underground work and the safety of the operators. 
     EFFECT: improved quality of the captured image in low light conditions and uneven distribution of lighting.

Abstract: FIELD: power engineering. 
     SUBSTANCE: invention relates to solar power engineering and to the field of household lighting and heating devices, and namely to devices for lighting and heating of cold and damp rooms with low temperature and low natural illumination: basements, corridors, vestibules, bathrooms and bathrooms, mines, underground car parks and garages, metro stations, and so forth. Stationary solar radiation concentrator comprises a converging radial Fresnel lens and a receiving gradient focus. In the concentrator in front of the focus of the narrowing lens there is a guiding bent in the form of a hemisphere reflector, on the inner surface of which there are reflecting annular micro prisms, and the input end of the gradient focon has the shape of a convex microlens and is located in the focus of the entire optical system, between the Fresnel lens and the reflector. Fixed solar radiation concentrator is based on successive narrowing and direction of light flux on the focon at first with a narrowing Fresnel lens, and then expanding reflector bent in the form of a hemisphere, with application on its surface of circular fragments conjugated prisms with a triangular cross-section. Final narrowing of the light flux is performed by a gradient focon which is located in the focus of the entire optical system. Reflector performs two functions simultaneously - expands the convergent light flux and directs this narrow flow to the input end of the gradient focon, which smoothly changes into the optical fiber, through which light is transported to the illuminated room. 
     EFFECT: such design makes it possible to create a flat sealed concentrator, with a minimum number of parts, which, without using mechanical servo systems, performs optical guidance to the Sun.
