Embodiment Construction

[0031] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0032] The present invention proposes a VCSEL array formed by multiple sub-arrays, the VCSEL array can be used as a light source for a laser projection device in a 3D imaging device, and a corresponding laser projection device and 3D imaging device are proposed based on this laser array, here The 3D imaging device is also called a depth camera. The value of each pixel in the image of the object captured by the depth camera represents the depth value between the corresponding point in space and the depth camera. In the following description, the laser array, laser projection device and depth camera will be described as examples, but it does not mean that this laser array can only be applied in the depth camera. Any other device that directly or indirectly uses the All technical solutions should be included in the protection sc...

Abstract

The invention discloses a VCSEL array light source, a pattern design method of the VCSEL array light source, a laser projection apparatus and 3D imaging equipment. The VCSEL array light source comprises a semiconductor substrate and a plurality of VCSEL light sources which are arranged on the semiconductor substrate in a two-dimensional array form; and the two-dimensional array is generated by at least one sub array through a conversion way. The VCSEL light sources distributed on the surface of the semiconductor substrate have extremely high irrelevance, so that the problem of low irrelevance of the VCSEL light sources in 3D imaging in the prior art can be solved; and the VCSEL array is mainly applied in a depth camera.

Description

technical field [0001] The invention relates to the fields of optics and electronics, in particular to a VCSEL array formed by a plurality of sub-arrays. Background technique [0002] 3D imaging, especially the 3D imaging technology used in the consumer field, will continue to impact or even replace the traditional 2D imaging technology. In addition to the 2D imaging capability of the target object, the 3D imaging technology can also obtain the depth information of the target object. According to the depth information 3D scanning, scene modeling, gesture interaction and other functions can be further realized. Depth cameras, especially structured light depth cameras or TOF (time-of-flight) depth cameras, are currently hardware devices commonly used for 3D imaging. [0003] The core component of the depth camera is the laser projection module. According to the different types of depth cameras, the structure and function of the laser projection module are also different. For ...
