Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that determine whether to illuminate a scene with electromagnetic radiation at a first wavelength or electromagnetic radiation at a second wavelength. An illuminator that is configured to selectively emit electromagnetic radiation at the first wavelength and at the second wavelength is triggered to emit electromagnetic radiation at the first wavelength instead of the second wavelength. A first voltage is applied to a first electrically active filter. A third voltage is applied to a second electrically active filter. A first image is obtained from a first sensor that senses electromagnetic radiation that passes through the first filter. A second image is obtained from a second sensor that senses electromagnetic radiation that passes through the second filter. A depth map is generated from the first image and the second image.
