Abstract

The invention provides an integrated imaging 3D projection display device without depth reversal. The device is composed of a projector and a micro mirror array. The projector directly projects a micro image array to behind the micro mirror array. The number of reflection units included in the micro mirror array is the same with that of image elements included in the micro image array, and the reflection units are aligned with the centers of the image elements. The reflection units of the micro mirror array reflect, gather and reduce light projected by the projector so as to reproduce a 3D image without depth reversal.

Description

technical field [0001] The invention relates to integrated imaging technology, in particular to an integrated imaging 3D projection display device without depth inversion. Background technique [0002] Integrated imaging includes two processes of 3D shooting and 3D display. In the process of 3D shooting, since each lens element that constitutes the microlens array has a unique imaging function, and each lens element records a small part of the information of the 3D scene from different angles, a corresponding image is generated on the back focal plane of each lens element. A tiny image with different angles of view is called an image element, so the microlens array records the information of different angles of the 3D scene on the back focal plane of the microlens array, forming a microimage array. During the 3D display process, the micro-image array is placed on the rear focal plane of the micro-lens array for display. According to the reversible principle of the optical p...
