Chemical imaging technology is a rapid examination technique that combines molecular spectroscopy and digital imaging, providing information on morphology, composition, structure, and concentration of a material. Among many other applications, chemical imaging offers an array of novel analytical testing methods, which limits sample preparation and provides high-quality imaging data essential in the detection of latent fingerprints. Luminescence chemical imaging and visible absorbance chemical imaging have been successfully applied to ninhydrin, DFO, cyanoacrylate, and luminescent dye-treated latent fingerprints, demonstrating the potential of this technology to aid forensic investigations. In addition, visible absorption chemical imaging has been applied successfully to visualize untreated latent fingerprints.
化学成像技术是一种将分子光谱学与数字成像相结合的快速检测技术，可提供有关材料的形态、组成、结构和浓度的信息。在众多其他应用中，化学成像提供了一系列新颖的分析测试方法，这些方法减少了样品制备，并提供了检测潜在指纹所需的高质量成像数据。发光化学成像和可见吸收化学成像已成功应用于茚三酮、1,8-二氮杂萘酮、氰基丙烯酸酯和经发光染料处理的潜在指纹，证明了该技术在协助法医调查方面的潜力。此外，可见吸收化学成像已成功应用于可视化未经处理的潜在指纹。
