微区域角分辨光谱测量系统
Micro-area angle-resolved spectroscopy measurement system
摘要
Abstract
To study the optical response of micro-area in surface plasmon nanostructures,we develop a mi-cro-area angle-resolved spectroscopy measurement system based on a coaxial rotating arm.The system ad-opts a micro-area remote excitation and collection optical path model based on a finite conjugate configura-tion,enabling an incident micro-area spot with a diameter of 32 μm.In addition,an angle-resolved mechanic-al system based on a coaxial rotating arm is constructed,realizing large-range directional angular excitation from 6.9° to 90°.Performance tests show that the system exhibits high stability,with a minimum angular res-olution of 0.12°.Through the reflection spectrum collection experiments on one-dimensional gratings and two-dimensional periodic nanostructures,the reliability of the system is further verified.The results demon-strate the advantages of the micro-area spot,which provide an effective technical means for the angle-re-solved spectroscopy characterization of micro and nanostructures.关键词
