  • Patent number: 9483617
    Abstract: Provided is a system and method for evaluating laser treatment, for converting the attribute of a laser beam and numerically evaluating proficiency of a laser treatment operator by processing data obtained by photographing the converted laser beam so as to use the evaluated data as training data. The laser treatment evaluating system includes an attenuation unit for attenuating intensity of a laser beam transmitted through a transmissive plate, a camera for photographing the laser beam transmitted through the attenuation unit, and an image data processing apparatus connected to the camera, for processing an image captured by the camera, tracking a trajectory of a laser beam on the transmissive plate, and calculating a distribution state of spots on which the laser beam on the transmissive plate is emitted.

  • Publication number: 20130237973
    Abstract: The present invention discloses a laser emission system comprising a laser emission device for irradiation a laser to an area of a targeted object; a monitoring device; a display unit for displaying an image captured by the monitoring device; and a control unit connected to the monitoring device and the display unit. Here, the control unit receives the information on a movement direction and a moving distance of the laser emission device and distinguishes between an area emitted with a laser by the laser emission device and an area which is not emitted with a laser, and then displays them on the display unit. Regardless of the perceived skill of the operator, the present invention prevents the irradiation of the area from being omitted and prevents the area from being excessively or insufficiently emitted in the laser treatment.
