一光波干涉之原理 1802年Thomas Young氏及1815年Fresnel氏等物理学家先后表明于光波干涉的理论和完成有名的光波干涉实验——Fresnel镜,奠立了光波干涉实验之基础,使以后的科学家们,无论在天文上、光波之研究上、以及近代的精密机械制造工作之度量上,都能利用光之干涉理论来进行超极精密工作之测量。1889至1895年,物理学家邁克逊氏设计了邁克逊光波干涉仪,并首先对巴黎的国际度量行局的“原尺”(International prototype)进行精密测量,以求得“原尺”长度和镉光谱中红色光波波长间的相互关系。 (镉光谱线中红色光波波长λ_R
A principle of lightwave interference Thomas Young in 1802 and Fresnel in 1815 and other physicists have shown that the theory of lightwave interference and the completion of the famous lightwave interference experiment - Fresnel mirror, laid the foundation for lightwave interference experiments, so that later Scientists can use the theory of light interference to measure ultra-precision work, both in astronomy, lightwave research, and the measurement of modern precision machinery manufacturing. From 1889 to 1895, physicist Mike Jackson designed the Michelson optical interferometer and first performed a precision measurement of the “International prototype” of the Paris International Bureau of Weights and Measures to obtain a “true length” and Correlation of red light wavelength in cadmium spectrum.
