COHERENT OPTICAL REFLECTOMETER FOR DETECTING VIBRATION ACTION Russian patent published in 2013 - IPC G01D5/353 

Abstract RU 2477838 C1

FIELD: physics.

SUBSTANCE: reflectometer has a pulse modulator and a pulsed radiation source connected to each other and a means of facilitating bidirectional transmission of radiation. The means of facilitating bidirectional transmission of radiation is connected to the pulsed radiation source, a sensitive fibre and through a photodetector to a control and processing unit, which is connected to the input of the pulse modulator. The connection between the means of facilitating bidirectional transmission of radiation and the pulsed radiation source is in form of two optical paths formed by two optical splitters. One of the splitters is connected to the output of the pulsed radiation source and the other to the means of facilitating bidirectional transmission of radiation. One of the optical paths has a delay line and the other has a phase modulator connected to the control and processing unit.

EFFECT: improved invention.
