FIELD: physics.
SUBSTANCE: apparatus has seven V-shaped fibre light guides (sensors) which lie in areas of possible cracking, three diode lasers, three optical radiation measuring receivers, a photoelectric signal processing unit and an information processing unit with software. The apparatus further includes seven adjustable resistors and one limiting resistor, a block of seven emitters, a block of seven receivers, a microcontroller and a transceiver. The apparatus realises the method of determining points of prefracture in structures.
EFFECT: high reliability of measuring optical signal variations in optical fibres.
