Abstract
A structured light generation device includes a first surface structure and a second surface structure, which are opposed to each other. The first surface structure includes a diffractive optical element. The second surface structure includes a lenticular lens structure. By the diffractive optical element, an incident dot beam is processed into plural dot beams with different sizes and different brightness values. By the lenticular lens structure, the each dot beam is expanded to a linear beam. After the single dot beam is processed by the structured light generation device, a structured light is generated. The structured light generation device can be applied to a projection system with a 3D gesture sensing control or detection device.
