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.

Optical device

An illuminator including a light source and an optical device is provided. The light source is configured to emit light. The optical device is configured to provide uniform illumination with at least one indicating mark after receiving light. The optical device includes a diffusing part and a directing part. The diffusing part is configured to provide uniform illumination. The directing part is configured to provide at least one indicating mark.

Illuminator

The present invention provides a projector including a light-emitting device, a diffraction optical element (DOE) and a switchable diffuser. The light-emitting device is arranged for generating a laser beam. The switchable diffuser is controlled by a control signal to diffuse or scatter received lights or not diffuse or scatter the received lights, wherein the laser beam passes through the DOE and the switchable diffuser to generate an output image of the projector.

Projector, electronic device having projector and associated control method

The present invention provides a projector, wherein the projector includes a light-emitting device, a lens module having a diffuser part and a lens part, and a DOE. In the operations of the projector, the light-emitting device is arranged for generating at least one laser beam, and the at least one laser beam passes through the diffuser part and the DOE to illuminate a field of view, and the at least one laser beam passes through the lens part and the DOE to generate a plurality of dots.

Projector, electronic device having projector, and method for obtaining depth information of image data

The present invention provides an electronic device, wherein the electronic device includes a projector and a controller. The projector includes a laser module and a lens module with a cover glass, wherein a laser beam generated from the laser module passes through the lens module to generate a projected image. The controller is coupled to the projector, and is arranged for determining if the cover glass is broken to generate a determination result, and controlling a power of the laser module according to the determination result.
