…is recorded as the steering is moved. This
pattern is produced by a standard refractive line generation lens followed by
a diffractive optic to produce multiple lines (i.e., multiple orders). The critical
parameters here are the grid shape and size, i.e., line linearity, parallelism,…

…over great distances or focused to a very small spot. Well-designed lasers produce a beam of light
that will expand ("diverge") only by the minimum amount prescribed by the laws of diffraction. For example, diffraction imposes that the minimum spot that
can be produced by a laser beam is…
