Abstract
A three-dimensional (3D) sensing system for determining a 3D profile of an object and a method are provided. The 3D sensing system includes a liquid crystal lens, a structure light source and a control circuit. The structure light source is configured to emit a structure light pattern with a plurality of dots on the object through the liquid crystal lens. The control circuit is configured to control the liquid crystal lens to separate the plurality of dots under a separating mode, and the control circuit is configured to control the liquid crystal lens to overlap the plurality of dots under an overlapping mode.
