摘　　要：基于扫描探针显微镜的近场超空间分辨指纹光谱技术在分子识别及组分鉴别方面具有极大的应用前景.扫描探针显微技术与不同的光谱联合使用,发展出了不同的具有纳米级分辨的指纹光谱技术,其中包括针尖增强拉曼散射光谱技术、纳米级分辨率的傅里叶变换红外光谱技术及散射式的扫描近场太赫兹光谱技术.这三种散射式的扫描近场光学显微技术在实现方式上有所不同,在近场指纹识别方面可以相互补充.该综述主要对三种近场超空间分辨指纹光谱技术的特点进行了深入地分析和比较,并且对这三种技术的研究现状及应用进行了总结.Scanning probe microscope（ SPM） based super-resolution near-field fingerprint microscopy is a promising technique for detecting molecular structures and identifying the composition of materials on the nanometer scale. In recent years,tip-enhanced Raman scattering,Fourier-transform infrared nanospectroscopy and scattering-type scanning near-field terahertz spectroscopy have been developed based on the combination of Raman scattering spectroscopy,infrared absorption spectroscopy and terahertz spectroscopy with a SPM,respectively. These scattering-type scanning near-field optical microscopy techniques are realized by using different experimental setups and can provide different but complementary information on the structure or components of materials. In this review,the characteristics of the above three techniques are examined and compared in depth,and the applications and recent progresses of them are also summarized concisely.
