| titleOfInvention | Structured light projector, image acquisition structure and electronics |
| abstract | The invention discloses a structured light projector. A structured light projector includes a substrate assembly, a lens barrel, a light source, a collimating element, and a diffractive optical element. The lens barrel includes a side wall of the lens barrel, and the side wall of the lens barrel and the base plate assembly together form a receiving cavity. The light source is disposed on the substrate assembly and used to emit laser light. The collimating element is used for collimating the laser and includes a plurality of lenses, which are arranged on the light-emitting light path of the light source, and the plurality of lenses include at least one first-type lens, at least one second-type lens made of glass material, and at least one liquid lens , the liquid lens can change the focal length under the action of voltage. The diffractive optical element is mounted on the lens barrel. The invention also discloses an image acquisition structure and an electronic device. The problem of temperature drift of the lens is improved by combining multiple lenses, and the temperature drift of the glass material of the second type of lens is small to reduce the temperature drift, and the liquid lens is used to change the focal length to solve the problem of reducing the accuracy of the laser pattern. question. |
