Paper Abstract

A new simple method of producing line beam from thin laser beam by only a spherical lens is proposed and some experiment results are given. The mechanism of the transformation is due to the large astigmatism of the lens. The evaluation to the generated beams and some related problems are discussed. This simple technique may be useful in 3D profile measurement by light-sectioning surface profile measurement of cylinder lens or reflector by laser scanning and other cases requiring line beam illumination.
