The aerial imaging technology based on volume holography is a new type of display technology,which has the characteristics of aerial imaging, without medium and the images being touched. Aerial imaging technology is introduced. In response to the display requirements of creating a real image, through theoretical calculations of holographic imaging, a two-step shooting optical path is designed with a focus on achieving a size of 100 mm at a height of 79.8 mmx99.4 mm real image with a field of view angle of 7.92° horizontally and 7.92° vertically.With the characteristic of floating in the air to form a real image, it can be combined with sensing technology to form a contactless operating system in the air, which provides new technological choices for developments in various industries.
