Abstract
A three-dimensional (3D) depth sensor may include: a plurality of light sources configured to irradiate light to an object, the light having different center wavelengths; an optical shutter configured to allow reflected light reflected from the object to pass through; and an image sensor configured to filter the reflected light having passed through the optical shutter and detect the filtered light.

A three-dimensional (3D) depth sensor comprising:
- a plurality of light sources configured to irradiate light to an object, the light having different center wavelengths;
- an optical shutter configured to allow reflected light reflected from the object to pass through;
- and
- an image sensor configured to filter the reflected light having passed through the optical shutter and detect the filtered light,
- wherein the plurality of light sources are configured to control intensity and a center wavelength of the light irradiated therefrom based on a magnitude of a driving voltage.
