    摘要： Disclosed is a laser processing device, which includes a processing beam source configured to irradiate a processing laser towards an object, a measuring beam source configured to irradiate a modulated measuring laser, an irradiator configured to align a path of the measuring laser with a path of the processing laser directed towards the object, a beam receiver configured to receive the measuring laser reflected from the object, an I/Q demodulator configured to calculate a phase difference between the measuring laser irradiated from the measuring beam source and the measuring laser received at the beam receiver, and a data processor configured to calculate a processed length of the object by using the phase difference. The invention can be used to measure the length of a laser-processed portion at the same time as the laser processing itself, so that the laser processing may be performed with improved precision.

    摘要： A method for reconstructing a three-dimensional structure using silhouette information on a two-dimensional plane is provided. The method includes: obtaining silhouette images; creating a cube on a three-dimensional space using the silhouette images; calculating vertex coordinates on a two-dimensional image plane by projecting eight vertices of the three-dimensional cube on a two-dimensional image plane of a first camera; dividing into multiple inner voxels by dividing sides formed by the eight vertices by a divider; dividing into a predetermined number of regions by dividing sides connecting the coordinates by a predetermined divider; assigning indices by matching cubes of the three-dimensional cube to square regions on the two-dimensional image plane in one to one manner; storing indices of regions where the square regions meets with a first silhouette image; and reconstructing three-dimensional structure by finding common indices through repeatedly performing the steps using other silhouette images.
