When shooting a hologram, it requires special optical equipments and a darkroom. If the darkroom is not large enough, it is not easy for many people to enter in the dark room. In addition, it is not easy to handle special and expensive optical equipments for beginners. When teaching holography in a class room, it is not convenient to bring these equipments. Therefore, we use Augmented Reality technology in this study to build a virtual optical system on the desk. The image of the real scene is acquired with a video camera. Then virtual optical elements are superposed through markers corresponding to each optical element. The user can change the position of the virtual optical element to build correct optical setup without the dark room and any special optical elements. With this system, people can simulate the assembling procedure of the optical system and we can expect to learn the basics to make a hologram for anyone easily.
