FIELD: physics.
SUBSTANCE: proposed device allows for exact measurements of internal spacing of smelt transfer torpedo ladles, using reference survey at primary industrial application (data are stored to memory device then) and following surveys by evaluation the difference with associated valid record; changes in brickwork, specifically, tear and wear, stone falls etc. According to invention device contains rotating probe head mounted on support bracket with hollow shaft. Provided mirror device is rigid relative to probe and used for radial deflection of beams axially incident relative to hollow shaft. And contrariwise, at that radiation of rigid transmitting device can originally be excited axially relative to hollow shaft and be radially transferred by mirror device. Radiation reflected from targets within object space can be deviated with mirror device to axis of hollow shaft and be supplied to rigid receiving device.
EFFECT: higher measurement accuracy.
