Abstract
A novel method for propagating light-knife by the reflection of Gaussian laser beams at a cylinder is put forward and the formula to appraise the geometry parameters of light knife is also derived. The experimental results show that the light-knife generated by using this method has advantages of less width variety, high contrast and large depth of field. It could be used as a line structure light in active 3D profile measuring systems.
