IPC: H03D3/26
Filed: 1982-03-12
Abstract: PURPOSE:To improve the S-shaped characteristics and to obtain a detection output of a low distortion factor, by shifting the 1st resonance frequency supplied to the 1st wave detecting circuit by DELTAf. CONSTITUTION:Wave detecting transistor (TR)Q4 and QB are connected to the positive and negative polarity terminals of a differential amplifier 1. A signal of a resonance frequency f1 decided by a coil L and capacitors C0 and C1 is supplied to the TRQA; while a signal of a resonance frequency f2 decided by the coil L and the capacitor C0 is supplied to the TRQB respectively. The terminal of the coil L connected to the TRQA is connected to an intermediate tap since the resonance frequency is shifted by DELTAf. In such a way, it is possible to improve the asymmetrical S-shaped characteristics that is due to the shift of the center frequency f0 by DELTAf. This enables the FM detection of a low distortion factor.

Abstract: PURPOSE: To non-destructively decide a refractive index distribution of an optical fiber preform core cane by selecting a wavelength so as to eliminate fringe diffraction effect caused by a refractive index fringe. CONSTITUTION: A light beam at a wavelength of 3395nm, which is suitable for eliminating fringe diffraction effect from a transmittance of a preform cane substantially made of silica, is applied 41 from a light source 40 to a measuring cell 42. The cell 42 made of a silica rectangular slab 43 holds a sample 44 in a hollow cylindrical part 45 and is filled with refractive index matching fluid between the sample 44 and the slab 43. The light beam is deflected so as to be emitted when it passes through the sample 44, and an outlet angle is measured by means of a conversion lens 64 on the basis of a Fourier transformation. The position of the beam is measured within a focal point face of the lens 64 by modulating the beam so that a phase difference between a chopper 47 and the reference beam 50 can be decided.  In this process, the cell 42 is moved upward and downward so as to generate a polarization function when the light beam passes through the sample 44, and this polarization function is converted into a refractive index distribution so as to be processed in the form of a signal.
