METHOD OF FORMMING GEOMETRIC FIGURE USING LIGHT BEAM AND APPARATUS FOR THE SAME

摘要

PURPOSE: A method for performing a specific surface of a geometric figure using a trace of a reflected light, and an apparatus for performing the same are provided to form a specific curve of a three dimensional figure by using a whole trace of a reflected light. CONSTITUTION: A light source(10) irradiates a light ray with a fixed width. A fixed angle is formed between a center axis and an optical axis of the light ray(L0) irradiated from the light source. A side surface of a cylinder type object is formed into a curved surface, and is positioned on an optical path. An object(20) partially has a cylinder type surface. A screen(30) is vertically installed with the optical axis of the light ray coming from the light source. A rotation center axis of a cylinder longitudinal direction of the cylinder type object is the same as y-axis in a three dimensional space having x-axis, y-axis, and z-axis.
