Abstract
A portable electronic device for measuring a distance Dbetween two points E, E, includes a visible and rotatable light emitter, an angle computing unit, a distance computing unit and an output unit. The light emitter generates a rotatable light beam capable of rotating from pointing in an initial direction to project to the point E. The initial direction is substantially perpendicular to a line defined by the points E, E. A distance Hbetween the light emitter and the line, and a distance Sfrom the point Eto the point of intersection of the line defined by the first and second points E, Ewith the initial direction, are known. The angle computing unit computes an angle defined by the visible light beam projecting to the point Eand the initial direction according to the rotatable light beam. The distance computing unit computes the distance Dbased on the angle, the distance Hand the distance S
