  • Laser projection module, depth camera and electronic device
    Patent number: 11525669
    Abstract: A laser projection module is provided. The laser projection module includes a substrate assembly, a lens barrel assembly, a light source, a diffractive optical element and a collimation element. The lens barrel assembly includes a lens barrel and a stop member connected to the lens barrel. The lens barrel is disposed on the substrate assembly and configured to define a receiving cavity together with the substrate assembly. The light source is disposed on the substrate assembly, accommodated in the receiving cavity, and configured to emit laser to the receiving cavity. The diffractive optical element and the collimation element are accommodated in the receiving cavity. The light source, the collimation element and the diffractive optical element are sequentially disposed in an optical path of the light source. The stop member is configured to prevent the diffractive optical element from moving in a light-emitting direction of the laser projection module.
