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.
