Abstract
Brillouin spectroscopy is an emerging tool for microscopic optical imaging as it allows for non-contact, non-invasive, direct assessment of the elastic properties of materials. However, strong elastic scattering and stray light from various sources often contaminate the Brillouin spectrum. A molecular absorption cell was introduced into the virtually imaged phased array (VIPA) based Brillouin spectroscopy setup to absorb the Rayleigh component, which resulted in a substantial improvement of the Brillouin spectrum quality.
摘要
布里渊光谱学是一种新兴的微观光学成像工具，因为它能够对材料的弹性特性进行非接触、非侵入性的直接评估。然而，来自各种来源的强弹性散射和杂散光常常会干扰布里渊光谱。在基于虚拟成像相控阵（VIPA）的布里渊光谱装置中引入了一个分子吸收池，以吸收瑞利成分，这使得布里渊光谱的质量得到了显著提高。
