Paper Abstract

When an axicon is illuminated under an angle different than the assumed one, its focal segment looses quality and broadens significantly. In order to compensate this aberration, harmful in scanning and metrological applications of axicons, a concept of an aberrationless axicon doublet working in the real time is proposed. The constant part of the doublet is an ordinary and conventional linear axicon, whereas the second, variable part, for which the application of spatial light modulator (SLM) device is proposed, introduces a phase shift completing the transmittance of the whole doublet to that of the corresponding elliptical axicon forming in a given moment a properly inclined focal segment.
