Nowadays, the 3D display technology has attracted great academic and industrial attention due to its rapid development and applications in providing more realistic, natural, and extra depth images far superior than the traditional 2D display. But traditional 3D techniques suffer from many drawbacks and hard to meet the requirement of commercialization. In the present study, the field reconstruction method of holograms is proposed for the first time to realize the display of true 3D image in free space which is more practical and better than traditional holographic technique in image quality. An optical switch array (OSA) and a projection lens are used to generate a series of 2D image slice, which can form a virtual 3D object, in free space. Then the light from the virtual object and reference light interference with each other forming an interferometric fringe on the screen and thus the 3D image of the virtual object is reconstructed in free space, timely. Meanwhile, the OSA can work as an image generator and sensor simultaneously which allows user to interact with the reconstructed 3D scenery without extra equipment.
