摘要
介绍一种新的红外高反射率绝对测量方法。这是采用双光路和可转动180°的双球镜反射谐振腔光路,测量反射率高次方的光学方法。反射率测量准确度达到5×10^(-4),重复精度好于2×10^(-4)。
This paper presents a new method of absoulte measurent for infra- red high-reflectance.Double beam are used and reflecting cavity of two spherical mirrors are constructed and rotated by 180°.Measuring beam is reflected light times on the surface of sample.The accuracy of measu- rement reflectance is 5×10^(-4)and the precision better than 2×10(-4),
