Abstract
A structured light projector and a method for structured light projection are disclosed. The structured light projector includes a projection module, a liquid crystal (LC) lens and a processor. The projection module is configured to project an optical pattern. The (LC) lens module is disposed over the projection module, and is configured to focus the optical pattern onto a region of space. The processor is configured to generate a control signal depending on an environment temperature of the projection module for controlling the LC lens.
