WebJan 2, 2004 · Optical vortices in focal regions are studied using the Debye approximation. We discuss how scalar vortices give rise to different intensity structures in the focal region for a certain class of apertures. WebOur PSF engineering techniques have been designed to work in the nonparaxial regime and are applied both to bright-field and single-photon fluorescence confocal micros- copy, and also to more elaborated architectures like 4Pi confocal microscopy.
