Abstract
An example apparatus includes a light projecting system, a light receiving system, and a controller. The light projecting system projects beams of light of a wavelength that is invisible. The beams form a pattern on a surface when the beams are incident upon the surface. The light receiving system acquires an image of the pattern on the surface. The controller calculates a distance to the surface based on the image. The light receiving system includes a lens, an imaging sensor, and a bandpass filter. The imaging sensor includes a first subset of photodetectors sensitive to wavelengths of light that are visible and a second subset of photodetectors sensitive to the wavelength of light that is invisible. The bandpass filter includes a first passband whose range corresponds to the wavelengths of light that are visible and a second passband whose range corresponds to the wavelength of light that is invisible.
