Title: Production of optical fiber preform
Inventor: KOMURA YUKIO
IPC: G02B6/00
Filed: 1985-08-14
Abstract: PURPOSE:To produce an optical fiber preform having desired refractive index distribution, stably, by radiating white X-ray to the core part and the circumferential part of a growing optical fiber preform under rotation, separating the transmitted ray into plural monochromatic X-rays, and controlling the preform- producing system according to the result of the spectrometry. CONSTITUTION:The white X-ray radiated from the X-ray source 5 is separated into X1 and X2 with the collimator 6 and radiated to the core part and the circumferential part of the growing optical fiber preform 4 under rotation. The white X-rays X1 and X2 transmitted through the core part and the circumferential part of the optical fiber preform 4 are passed through the collimators 9, 10, separated into monochromatic X-rays having specific energy levels E1, E2 by single crystals 11, 12, 13 and 14 and introduced into each X-ray detection system 7, 8. The energy E1, E2 of the incident X-rays are measured by the detection systems and the signal is inputted to a computer 15. The computer 15 analyzes the composition of the growing preform based on the inputted signal and controls the preform-production system to the optimum state according to the result of analysis. An optical fiber preform 4 having desired refractive index can be produced stably by this process.

IPC: G01R15/08
Filed: 1986-07-30
Abstract: PURPOSE:To perform automatic switching to a proper level in a dynamic range and to preclude deterioration in accuracy due to nonlinear distortion, etc., by performing the switching to the proper range when the peak value of an input signal to be measured exceeds a permissible input range. CONSTITUTION:The signal to be measured from a signal source 20 is applied to an absolute value detecting circuit 2 through an automatic range circuit 1. The output of an absolute value/execution value converting circuit 3 is applied to a comparator 5 through an A/D converter 4 and compared with the upper- limit and lower-limit reference values of level comparison from a reference value setting circuit 8, so that a range-down signal V1' or range-up signal V2' is sent out. An absolute value detection output, on the other hand, is applied to a peak holding circuit 6 as well, thereby generating a preferential range-down signal V1 when the peak value signal exceeds the upper-limit reference value L1. When the automatic range circuit 1 is switched to the proper range with the output of a gate circuit 9, a reset signal is generated and the peak holding circuit 6 is reset.

Abstract: PURPOSE:To reduce the size of the sensor and to reduce the thickness of a signal transmission part by applying a bias which has a 45 deg. angle of rotation to polarized light which passes through a Faraday effect element while a magnetic field to be measured is zero. CONSTITUTION:A polarizer 3, the Faraday effect element 1, and a reflecting mirror 2 are aligned in this order coaxially with the optical axis of a lens 5 which is coupled with a terminal of a single-core optical fiber 6 and an annular permanent magnet 4 is arranged surrounding the Faraday effect element 1 and polarizer 3.
