The structured light projector includes a projection module, a processor. The projection module is configured to project an optical pattern onto a region of space, and includes a light source, a diffractive optical element and a liquid crystal lens. The light source is configured to generate a light beam. The diffractive optical element is configured to convert the light beam into the optical pattern. The liquid crystal lens is interposed between the light source and the diffractive optical element, and is configured to collimate the light beam. The processor is configured to generate a control signal depending on an environment temperature of the projection module for controlling the liquid crystal lens."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Structured light projector","description":"A structured light projector and a method for structured light projection are disclosed.
