Title: Optical pulse train measuring method
Inventor: TOMARU TATSUYA
IPC: G01J11/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for acquiring the phase information of autocorrelation with relatively high sensitivity even at the time of low intensity of light without substantially limiting the measurable wavelength range. SOLUTION: A light of frequency f0 emitted from a light source 1 is introduced to an interferometer 2 having two optical paths, e.g. a Mach-Zehnder(MZ) interferometer. The two optical path interferometer 2 has a roll of providing an optical path length difference and a roll for enabling heterodyne detection by imparting a frequency difference to the light between two optical paths. A light transmitted through the two optical path interferometer 2 is converted through a light receiver 3 into an electric signal which is then processed for each spectrum through an intensity analyzer 4 thus obtaining an autocorrelation.  According to the method, not only a normal frequency difference component is taken out but the components, produced by adding the frequency difference to integer times of modulation frequency (repetitive frequency) of light source or subtracting the frequency difference therefrom, are measured simultaneously thus completing the information.

Abstract: PURPOSE:To prevent a shaft of inserting frame from coming off, and obtain a firm and durable construction by a method wherein an inserting frame of gasket mounted freely rotatably centering around a supporting shaft is provided with an inserting part and protruding part, and when a lid of dust chamber is tried to be shut without inserting the gasket of dust bag, closing is blocked by the contact of the inserting part and protruding part with the lid of dust chamber. CONSTITUTION:An inserting frame 5 to insert and hold a gasket of dust bag is fitted into a bearing hole 8 made on a supporting board 7 in a dust chamber 2 with its supporting shaft 9 freely rotatable, and is energized counterclockwise by a spring 10. This inserting frame 5 is provided with an inserting frame 11 to insert the gasket of dust bag and protruding part 12 made opposite to the supporting shaft 9. When a dust chamber lid 3 is tried to be shut without mounting the dust bag, the protruding part 12 comes into contact with a rib 13 formed in the dust chamber 3, and the inserting frame 11 also comes into contact with an inserting board 14 forming the internal wall of the dust chamber 3 to prevent the dust chamber lid 3 from being shut. And because the inserting frame 5 supports the dust chamber lid 3 at two parts on the right and left centering around the supporting shaft 9, the supporting shaft 9 is not subjected to an excessive force or moment, thereby is not liable to come off or broken down together with the bearing hole 8.
