Title:
計測装置及び計測方法
Document Type and Number:
Japanese Patent JP6782470
Kind Code:
B2
Abstract:
A measurement apparatus includes a light source, an interferometer, a light receiver, and a signal processor. The light source emits laser light to a scatterer in the atmosphere. The laser light has multiple oscillation frequencies separated from each other at equal frequency intervals. The interferometer produces interference in scattered light generated as a result of the laser light being scattered by the scatterer. The light receiver receives Mie scattered light included in the scattered light subjected to the interference produced by the interferometer and generates a signal. The signal processor detects the quantity of the Mie scattered light based on the signal. Each of the equal frequency intervals is smaller than the full width at half maximum of the peak of a frequency spectrum of Rayleigh scattered light. The Rayleigh scattered light is generated as a result of the laser light being scattered by molecules forming the atmosphere.
