FIELD: physics, signalling.

SUBSTANCE: invention relates to making alarm signals and devices for indicating overshoot of given deformation limits of the surface of monitored objects. The method of making signalling devices which are triggered by interruption of light flux during deformation of the surface of a monitored object includes an emitter which is optically connected through a flexible linear optical guide with a photodetector, and involves making and assembling the said components on the surface of the monitored object. After making the flexible glass optical guide with polished lateral surfaces, a thin light-reflecting layer is deposited on the said lateral surfaces and the glass of the optical guide is subjected to radiation toning with electromagnetic X-ray or gamma-radiation with dose of up to 10 kGy. The optical guide is then rigidly attached to the surface of the monitored object and a beam of fine-focused pulsed or continuous laser radiation with focal distance several times larger than the wavelength of the optical guide is transmitted through the optical guide. Wavelength of the laser radiation corresponds to the transparency range of the glass and the laser radiation has energy of up to 50 mJ. The radiation is transmitted for 60 s, which is sufficient for formation of a narrow channel in the glass on the entire length of the optical guide. During formation of the channel, transparency of the glass along the axis of propagation of the processing laser radiation is restored.

EFFECT: increased reliability of operation of signalling devices made using the proposed method.
