KeywordsĪlfano, R.R.: The Supercontinuum Laser Source. Thus, our system is able to achieve high-speed and high-accuracy 2D positioning of light sources and 3D scanning of scenes. Line imaging has several advantages over 2D sensors: high frame rate, high dynamic range, high fill-factor with additional on-chip computation, low cost beyond the visible spectrum, and high energy efficiency when used with line illumination. We demonstrate our approach in two applications: (a) fast passive imaging of sparse light sources like street lamps, headlights at night and LED-based motion capture, and (b) structured light 3D scanning with line illumination and line sensing. We show several extensions of our system to improve the accuracy of the 2D positioning and expand the effective field of view. We derive a detailed image formation model and a learning-based algorithm for 2D position estimation. We exploit this principle to recover 2D and even 3D positions from only line images. When light passes through a diffraction grating, it disperses as a function of wavelength. We present a novel computational imaging principle that combines diffractive optics with line (1D) sensing.
