Title: Method and device for measuring mode double refractive index of birefringent fiber
Inventor: TAKADA KAZUMASA
IPC: G01M11/02
Filed: 1987-11-30
Abstract: PURPOSE:To measure a mode double refractive index of optional wavelength with high accuracy and to easily obtain the transmission characteristics of the birefringent fiber by performing the Fourier transform of two interferograms measured by a Michelson interferometer. CONSTITUTION:Projection light from the birefringent fiber to be measured is made incident on the Michelson interferometer consisting of a beam splitter 14 and two right-angle concave mirrors 15 and 16. Incident light beams are propagated through different optical paths and multiplexed to interfere with each other. In this case, interferograms are formed nearby the origin of the difference l=0 between the two optical paths in the interferometer and at a point slightly distant from the origin as one concave mirror 16 of the interferometer is moved as shown by an arrow. Those two interferograms are measured and processed by Fourier transform and its ratio is calculated, so that a component with slow variation is generated in the phase term of the ratio. The mode double refractive index is found from the element of a position term with the slow variation and the value is as accurate as the variation is slow. Further, the loss ratio of both modes is found from the ratio after the Fourier transform.

Abstract: PURPOSE:To prevent frequency-shifted laser beams from being mixed with laser beams whose frequency is not shifted by shifting the frequency of a part of laser beams outputted from a laser oscillator for main oscillator and injecting the frequency-shifted laser beams as beams for controlling the frequency of a laser oscillator for a local oscillator. CONSTITUTION:Laser beams 2 outputted from the main oscillator 1 are divided into laser beams 11 whose frequency is shifted by a frequency shifter 9 such as an A-O element and laser beams 10 whose frequency is not shifted. The laser beams 10 are transmitted to a target by a scanning mirror 5 similarly to the ordinary method as transmitted light 6. On the other hand, the laser beams 11 are injected into the other laser oscillator consisting of a laser tube 16, an output mirror 18, a refractive grating 17, and a phase controlling etalon 19 through the etalon 19. The oscillation frequency of the laser oscillator can be oscillated at the frequency tuned only with the frequency of the frequency- shifted laser beams, and in case of tuning the frequency, frequency tuning can be more easily executed by finely tuning the driving frequency of the A-O element.
