布里渊光谱是一种新兴的显微光学成像工具，因为它允许非接触，非侵入性，直接评估材料的弹性性能。然而，强弹性散射和来自各种源的杂散光经常污染布里渊频谱。在基于虚拟成像相控阵（VIPA）的布里渊光谱系统中引入分子吸收池，吸收瑞利分量，使布里渊光谱质量得到显著改善。(C)2014年美国光学学会
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.
