Example Embodiment

[0036] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the embodiments of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0037] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is said to be "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for fixing or circuit connection.

[0038] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertica...

Abstract

The invention discloses an integrated beam-splitting scanning unit. The integrated beam-splitting scanning unit comprises a first transparent substrate, a second transparent substrate, a liquid crystal layer and a beam splitting unit, wherein the liquid crystal layer is arranged between the first transparent substrate and the second transparent substrate and is used for deflecting an incident light beam to achieve scanning, and the beam splitting unit is arranged on the first transparent substrate and/or the second transparent substrate and is used for splitting the incident light beam. By reasonably arranging the beam splitting unit and a scanning unit, the equipment volume is reduced, and high integration is achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an integrated beam splitting scanning unit and a manufacturing method thereof. Background technique [0002] Using the principle of time of flight (Time of Flight) and the principle of structured light, the distance measurement of the target can be carried out to obtain the depth image containing the depth value of the target, and further based on the depth image, functions such as 3D reconstruction, face recognition, and human-computer interaction can be realized. The distance measurement system has been widely used in consumer electronics, unmanned driving, AR / VR and other fields. [0003] The distance measurement system based on the time-of-flight principle and the principle of structured light generally includes a beam emitter and a collector. The light source in the emitter emits a beam of light to the target space to provide illumination, and the collector receives the b...
