Abstract
Device for taking three-dimensional and temporal optical imprints in color, including a three-dimensional dental imaging device that does not employ structured light projection. The device includes a stereo camera having at least two CCD or CMOS color sensors in preset positions, an optical system of fixed and preset focal length, an LED lighting system, and an electronic system located behind or near the sensor, controlling the latter but also the LEDs illuminating the imprint capture region. The system includes a central processing unit and a card for controlling said LEDs. The sensors are distributed over all or part of a dental arch, being placed in a sort of optical impression tray allowing a complete image of the arch to be captured in a single exposure.
