Polarization distribution of the focused beam reduced the focal area in an optical system with high numerical aperture (NA). Focal intensity distribution was measured using knife edge method setup. An incoming beam is focused by a microscope objective onto a specially designed p-i-n photodiode, where parts of the light sensitive area were covered with a sharp edged gold pad. By measuring the dependence of the photocurrent on the translation distance for different translation directions and orientations of the gold pad a reconstruction of the shape of the focus is possible by applying the Radon back-transformation.
