title: Design of single-element laser-beam shape projectors.
abstract: The design and fabrication of several single-element laser-beam projectors are described. These projectors take a Gaussian laser beam and expand it into a uniform intensity diverging shape, which can be either a single line, circle, cross, star, or a D. Each element consists of a single segmented surface designed so as to produce the required projected shape.
