ABSTRACT:
A confocal microscope apparatus has a confocal scanner for scanning a sample with shifting a focal position of a light beam in a direction perpendicular to an optical axis, a moving mechanism for moving the focal position of the light beam in an optical axis direction, a camera for picking up an image of the sample with the light beam, and a movement control unit for controlling the moving mechanism to move the focal position of the light beam by a predetermined distance in the optical axis direction for every vertical synchronizing signal of the camera in synchronization with the vertical synchronizing signal. A high-speed three-dimensional image can be displayed in such that while measuring the sample, two or more slice images in such an arrangement on a common screen that their positions relative to the sample enables to be grasped.
