Title:
3D IMAGING SYSTEM AND APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/128097
Kind Code:
A1
Abstract:
A three-dimensional (3D) imaging system and apparatus thereof. A display source (10) emits a main light beam. After being transmitted and reflected by a semi-transmissive semi-reflective mirror (30), the main light beam is divided into a first sub-light beam and a second sub-light beam. The first sub-light beam is reflected to an observation area (50) to be observed by human eyes, so as to form to a first image (S1). The second sub-light beam is transmitted to a retroreflective mirror (40), emitted with position shifted in a reverse direction by the retroreflective mirror (40), transmitted or reflected to the display (20) by means of the semi-transmissive semi-reflective mirror (30), then reflected to the semi-transmissive semi-reflective mirror (30) by means of the display (20), and finally transmitted or reflected, by means of the semi-transmissive semi-reflective mirror (30), to the observation area (50) to be observed by the human eyes, so as to form to a second image (S2). The first image (S1) and the second image (S2) are superposed to form a 3D image. The 3D imaging system can implement 3D projection imaging merely by one display source (10), and the positions of the first image (S1) and the second image (S2) are relatively precise.
