论文摘要
中红外(MIR)范围内的光谱成像提供了各种样品的同时形态和化学信息。但是,当前的miR技术很难以与实时过程兼容的采集速率在广泛的光谱范围内产生高清图像。我们提出了一种基于暂时性光学miR脉冲的非分级两光子吸收的新型光谱成像技术。这种新方法避免了复杂的图像处理或重建,并可以在一秒钟内以高像素密度以高像素密度对光谱数据立方体进行高速获取。
Spectral imaging in the mid-infrared (MIR) range provides simultaneous morphological and chemical information of a wide variety of samples. However, current MIR technologies struggle to produce high-definition images over a broad spectral range at acquisition rates that are compatible with real-time processes. We present a novel spectral imaging technique based on non-degenerate two-photon absorption of temporally chirped optical MIR pulses. This new approach avoids complex image processing or reconstruction and enables high-speed acquisition of spectral data cubes [xyw] at high pixel density in under a second.
