FIELD: physics. ^ SUBSTANCE: laser system includes a set of laser sources, each of which allows for adjustment on emission of electromagnetic waves and at least one adjustment controller for adjusting and tying each light beam to the wavelength of the spectral line of the required width. The system also includes a transmitter for transmitting each light beam for illuminating one or more targets, and a receiver for receiving light reflected from the targets and converting the reflected light into electrical signals for identification and/or quantitative evaluation of the target. The system additionally includes N tunable lasers, where M of the N lasers are tuned to wavelength which is partially absorbed by targets, and L of the N (one or more) lasers are tuned to wavelength which is not absorbed by targets. ^ EFFECT: invention increases accuracy of detecting leakages in pipelines. ^ 19 cl, 8 dwg |
