PURPOSE: An apparatus and a method for automated counting of asbestos fibers and a slide used for the same are provided to automatically count asbestos fibers included in a sample by analyzing images of the asbestos fibers, thereby reducing time and efforts required for analysis and increasing detection accuracy. CONSTITUTION: A drive unit (130) moves a slide, in which an asbestos fiber sample is put, intermittently in a regular distance. A signal delay unit (210) has a waveform generator that receives an input signal generated whenever the drive unit starts an operation intermittently, amplifies the signal to generate a TTL signal for delaying the input signal. A trigger connect unit (220) receives a delay signal delayed by the signal delay unit. A photographing unit (140) takes a photograph of the slide according to the delay signal input by the trigger connect unit. An image processing unit processes the photographed image to extract asbestos fibers existing in the slide as data and count the asbestos fibers.
