Abstract
An angular velocity correcting optical device receives a sinusoidally swept input light beam and outputs a non-sinusoidally swept output beam. The output beam may have a constant angular velocity. The output beam may have a constant pitch on a target surface for a constant periodicity pulsed light beam. Optical surfaces may be freeform surfaces specified by polynomials.
