这项研究提出了一种对石棉纤维进行成像和计数的新方法。这种方法将用于成像纤维的微分干涉对比 (DIC) 显微镜原理与成像程序相结合，以自动评估其浓度。石棉通常通过光学显微镜或电子显微镜方法检测。虽然光学显微镜技术（例如相差显微镜和偏光显微镜）快速且廉价，但由于分辨率低，无法确保彻底检查。相比之下，电子显微镜方法（如透射电子显微镜和扫描电子显微镜）可提供高分辨率图像，但价格昂贵且相关技术尚未广泛应用。因此，本工作提出了用于检测石棉纤维的DIC方法，因为它可以克服现有方法的许多缺点。它在便携式测量设备中也具有良好的应用潜力，可以在可能接触的位置检测石棉。
This study presents a new method for imaging and counting the concentration of asbestos fibers. This approach combines the principle of differential interference contrast (DIC) microscopy for imaging fibers with an imaging program to automatically assess their concentration. Asbestos is typically detected by optical microscopy or electron microscopy methods. While optical microscopy techniques (such as phase contrast microscopy and polarized light microscopy) are fast and inexpensive, they cannot ensure a thorough examination due to their low resolutions. In contrast, electron microscopy methods (such as transmission electron microscopy and scanning electron microscopy) provide high resolutions images, but are expensive and the related technology is not widely available.This work thus proposes the DIC method for detecting asbestos fibers, as it can overcome many of the disadvantages of existing methods. It also has good potential for use in portable measuring devices, which can detect asbestos right at the location of possible exposure.
