- 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.
