DEVICE FOR IMAGE ACQUISITION OF OBJECT LOCATED IN RADIATION HAZARDOUS ZONE Russian patent published in 2010 - IPC G21C17/08 G21C17/116 

FIELD: power industry.

SUBSTANCE: device includes mirror labyrinth in radiation-proof material, with deflecting mirrors and inlet channel to which protective casing with inlet opening is adjacent on the side of "dirty" room, in which there arranged is system of deflecting mirrors. System consisting of two inlet and two outlet mirrors provides the possibility of projecting the view angle which is large enough at considerable deflection of labyrinth axis from direction of observation to relatively small hole of inlet channel of mirror labyrinth. To outlet channel of mirror labyrinth there adjacent is recording unit with the projection lens and photoreceiving digital matrix connected by means of cable to external processor control unit and visualisation of image. Owing to the matrix structure of photoreceiver used, the high quality of output image is provided. At that, photoreceiving matrix of digital photorecorder of the image is protected as much as possible against penetration of ionising radiation to it because mirror labyrinth performs the function of radiation collimator.

EFFECT: rigid connection of optic system of image transfer to certain section of the observed area provides uniformity of the image perception and allows using it for shaping the appropriate control commands.
