Ushakova, K. Van den Berg, Q. Pereira, S.F. Urbach, H.P. Faculty Applied Sciences Department ImPhys/Imaging Physics Date 2015-03-12 Abstract A fast noninvasive method based on scattering from a focused radially polarized light to detect and localize subwavelength nanoparticles on a substrate is presented. The technique relies on polarization matching in the far field between scattered and spurious reflected fields. Results show a localization uncertainty of ?10?4?2 is possible for a particle of area ??2/16. The effect of simple pupil shaping is also shown.
