近些年来，空间偏移拉曼光谱（SORS）能够高效地检测深藏于强散射性干扰介质中的目标物，在各种无损检测领域被广泛应用，同时人们对空间偏移拉曼光谱的性能特征也进行了广泛而深入的研究。然而，迄今为止，还缺乏对 SORS 检测不同光学特性材料的详细研究。本研究旨在通过构建一个简明的双层模型来填补这一空白。在该模型中，两种不同光学性质的干扰物质被覆盖在目标物质上，通过分析表层干扰物和底层目标材料的拉曼散射信号强度，我们研究了物质散射性质的不同对SORS检测结果的影响。结果表面，相同检测条件下，表层干扰物散射能力越强，需要的检测空间偏移量越大。我们的研究证明了SORS 技术在穿透表层结构进行无损检测应用中的巨大潜力，并提供了对各种材料SORS 特性的全面了解。

In recent years, Spatially Offset Raman Spectroscopy (SORS) has gained significant applications due to its unique and efficient capability to detect target substances concealed within strongly scattering interfering media. Extensive and profound investigations have been conducted to demonstrate the performance characteristics of SORS. However, there is a lack of a comprehensive study exploring the detection of materials with varying optical properties by SORS. This research endeavors to bridge this gap by constructing a concise bilayer model. In this model, two distinct interferents with different optical properties are layered onto the target material. Through the analysis of the Raman intensities originating from the surface interferent and the underlying target material, we investigated the SORS performance when probing substances with varying degrees of scattering. Our findings indicate that under identical detection conditions, the higher scattering surface interferent need a larger spatial offset for effective detection by SORS. Consequently, this study demonstrates the substantial potential of SORS technology in non-invasive detection applications for sublayer components. Moreover, it provides a comprehensive understanding of the SORS.
