Paper Abstract

An afocal optical system designed to be attached to a conical optical beam deflector is discussed. The conical beam deflector generates a collimated optical beam that rotates along a cone-shaped trajectory in space. This output beam is then fed to the afocal attachment, a telescope, designed to tailor the beam characteristics to suit a particular application. For many applications, the afocal attachment functions as a beam expander and modifies three characteristics of the input beam. First, it expands the input beam diameter to an acceptable level. Then, it inevitably reduces the apex cone angle of the beam due to the inherent property of a telescope. Third, the stationary plane, the plane where the apex of the cone resides, is magnified and transferred to the conjugate image plane.
