The method of image acquisition and measurement apparatus of the inclination of the slide

[Problems] To provide a rapid measurement of the tilt slide an image acquisition apparatus and method for measuring the inclination of the carrier sheet for. [Solution] An image acquisition apparatus provided with: a stage, a stage placed slide, the slide is placed on a glass slide with and covered with a cover glass sample; stage moving means for moving stage; detecting means for detecting the position of the sample on the slide; from the collimator for directing the laser beam so that the inclination of the slide is detected, from the stage of mounting the mounted slides opposite to the side of the sample guiding the laser beam; and a control unit for controlling the stage moving unit such that the laser beam guided to the position of the sample on a slide, for controlling the inclination of the self-test collimator.
