摘要
基于体全息的空中成像技术是一种新型的显示技术,具有空中成实像、无需任何介质和影像可触摸的特点.介绍了空中成像技术.针对空中成实像的显示需求,通过对全息成像的理论计算,设计了两步拍摄光路,实现了在高度100 mm处,形成大小79.8 mmx99.4 mm的实像,视场角为水平7.92°,垂直7.92°.结合传感技术形成空中无接触操作系统,该系统具有视觉体验和无接触的新型交互特点,为各行业发展提供新的技术选择.
Abstract
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 tech-nology is introduced.In response to the display requirements of creating a real image,through theoretical calcula-tions 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 mm x 99.4 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 in-dustries.
