Problems solved by technology
[0002] Laser projectors need to set diffractive optical elements (DOE) on the laser emission path, and the diffractive optical elements are usually glued directly to the lens barrel of the laser projector, and the glue is prone to failure, causing the diffractive optical elements to fall off. And the laser is easy to burn the user after being emitted directly without diffractive optical elements

The electronic equipment, image acquisition device and laser projector disclosed in the present invention include a substrate component, a lens barrel, and a diffractive optical component. The lens barrel includes a side wall of the lens barrel arranged on the substrate assembly, the side wall of the lens barrel includes a first surface and a second surface opposite to each other, and the second surface is combined with the substrate assembly. The diffractive optical assembly is arranged on the first surface, the diffractive optical assembly includes a fixedly connected diffractive optical element and a top cover, the diffractive optical element is located inside the lens barrel, and the top cover is at least partially located outside the lens barrel and clamps the lens barrel together with the diffractive optical element . By setting a fixedly connected diffractive optical element and a top cover, the diffractive optical element and the top cover can hold the lens barrel together, the diffractive optical component will not be flipped relative to the lens barrel, and the diffractive optical element is not easy to fall off, preventing the laser from not passing through the diffractive optics The element burns the user after being fired directly, which improves the safety level of the user using the laser projector.
Description
technical field [0001] The present invention relates to the field of optical and electronic technologies, and more specifically, to a laser projector, an image acquisition device and electronic equipment. Background technique [0002] Laser projectors need to set diffractive optical elements (DOE) on the laser emission path, and the diffractive optical elements are usually glued directly to the lens barrel of the laser projector, and the glue is prone to failure, causing the diffractive optical elements to fall off. And the laser is easy to burn the user after being emitted directly without passing through the diffractive optical element.
