Abstract
An optical device including a Vertical-Cavity Surface-Emitting Laser (VCSEL) light source and a lens array is provided. The VCSEL light source is configured to emit light with at least one light dot. The lens array is configured to receive light emitting from the VCSEL light source and then project a structured light. The structured light includes a dot pattern having number of light dots. Plural convex lenses are arranged along a first surface of the lens array. The convex lenses are configured to generate the light dots of the dot pattern.
