  • Color scannerless range imaging system using an electromechanical grating
    Patent number: 6507706
    Abstract: A scannerless range imaging system includes an illumination system and an electromechanical light modulator. The illumination system illuminates objects in the scene with modulated illumination of a predetermined modulation frequency, and the modulated illumination reflected from objects in the scene incorporates a phase delay corresponding to the distance of the objects from the range imaging system. The electromechanical light modulator, which is positioned in an optical path of the reflected illumination, operates at a reference frequency that corresponds to the predetermined modulation frequency and accordingly modulates the modulated illumination reflected from the object, thereby generating a phase image from the interference between the reference frequency and the reflected modulated illumination.
