AI Technical Summary

Problems solved by technology

However, the VCSEL has a high temperature when it is powered on, and it is difficult to dissipate the heat quickly when it is uploaded to the optical device. The heat generated by the VCSEL can easily cause the deformation of the optical device, and eventually lead to the failure of the structured light emitted by the optical projection device.

Embodiment Construction

[0017] The carrying seat, its forming method, and optical projection device provided by the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "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 both fixing and circuit communication.

[0019] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only...

Description

technical field [0001] The invention relates to the field of electronic and optical devices, in particular to an optical projection device. Background technique [0002] The depth camera can obtain the depth information of the target to realize 3D scanning, scene modeling, and gesture interaction. Compared with the currently widely used RGB camera, the depth camera is gradually being valued by all walks of life. For example, the combination of depth camera, TV, computer, etc. can realize somatosensory games to achieve the effect of two-in-one game and fitness. In addition, Google's tango project is committed to bringing depth cameras to mobile devices, such as tablets and mobile phones, so as to bring a completely subversive experience. For example, it can realize a very real AR game experience, and can use it for indoor map creation and navigation. and other functions. [0003] The core component of the depth camera is the optical projection device. With the continuous ex...
