Abstract
A longitudinal interference fringe pattern projection lens with a lens body is provided. The lens body includes a lens first surface that has two convex portions or two concave portions that extend in parallel to each other in a constant direction and have the same shape, and a lens second surface. Laser light passing through one convex or concave portion interferes with laser light passing through the other convex or concave portion to form a longitudinal interference fringe pattern.
