| Abstract | We compared aberrations produced by an axicon and a lens. Using the wave aberration theory and the point spread function of a coherent system, we analyzed and compared the light intensity distributions of the spot created by an axicon and by a lens aberrated by astigmatism and coma. We also experimentally observed the aberrated light spots created by an axicon. We found that the beam spot of an axicon is aected only by astigmatism and not by coma, while the point created by a lens is blurred by both astigmatism and coma. This implies that the scanning optical system that incorporates an axicon is easy to correct the aberrations and achieves high resolution and high contrast imaging with a wide ®eld of view.
