Abstract

The invention provides a TOF module, intelligent equipment and a manufacturing method of an optical diffuser. The TOF module comprises a transmitting end assembly, the transmitting end assembly comprises a VCSEL light source and an optical diffuser which are arranged in sequence, and the optical diffuser is located on the emergent side of the VCSEL light source; a receiving end assembly; and the number of the light guide columns is one or more, and at least one light guide column is arranged in the transmitting end assembly and located at the outlet of the transmitting end assembly. According to the TOF module, the problem that the TOF module in the prior art is large in outlet aperture is solved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence three-dimensional imaging equipment, and in particular, to a method for manufacturing a TOF module, an intelligent device and an optical diffuser. Background technique [0002] The three imaging methods of binocular, structured light and TOF module are currently the mainstream choices for major manufacturers to achieve 3D imaging. Among the above three 3D imaging methods, the accuracy of binocular is low, the structure of structured light is complex and the cost is high, while TOF The module has sufficient accuracy and a slightly lower cost, and there is a trend of popular promotion. [0003] With the continuous upgrading of the mobile phone field, full-screen mobile phones have gradually become the main factor for the public to choose mobile phones. Full-screen is a definition of the mobile phone industry for the design of ultra-high screen-to-body mobile phones. The literal inte...
