Abstract
A method of correcting an optical axis of a laser projecting device is provided. According to this method, a cylindrical tubular member is provided, the tubular member made of a deformable material and having a base section, and a laser generation unit mounted inside the base section and adapted to project a laser beam along an optical axis. The tubular member is also provided with an extension section and a reduced-diameter circumferential groove between the base section and the extension section. Thereafter, the tubular member is rotated while projecting a laser beam from the tubular member towards a reference point in front of the tubular member that corresponds to a rotational axis of the tubular member. A spatial deviation between the optical axis and the reference point is detected, and the base section of the tubular member is deformed with respect to the extension section about the circumferential groove, and based on the spatial deviation, to cause the base section to be angularly displaced with respect to the tubular member until the optical axis and the rotational axis coincide.
