Improved axial resolution by point-spread autocorrelation function imaging.
Based on an interferometric spatial autocorrelation of two shifted point-spread functions combined with confocal detection, we demonstrate that the point-spread autocorrelation function technique provides improved axial resolution compared with conventional confocal imaging. The principle of the technique is demonstrated for a one-sided f luorescing step object.
متن کاملMeasurement of the 4Pkonfocal point spread function prow& 75 nm axial resolution
In a 4Pi-confocal microscope the specimen is illuminated and observed coherently from above and below such that the numerical aperture is increased [S. W. Hell, European Patent Application 91121368.4 (filed 1990, published 1992), S. W. Hell and E. H. K. Stelzer, J. Opt. Sot. Am. A9,2159 (.1992)]. The point spread functions of 4Pi-confocal and confocal microscopes were measured. Our measurements...

متن کاملImage Resolution Enhancement Using Spatially Invariant Point Spread Function
This paper presents an image resolution enhancement algorithm using spatially invariant point spread function. Point spread function is used to constrain the solution space. This parameter is computed at each iteration step using partially restored image at each iteration, and High pass filter is used to impose the degree of edge smoothness on the solution. The resulting iterative algorithm exh...
متن کاملIsotropic 3D Super-resolution Imaging with a Self-bending Point Spread Function
Airy beams maintain their intensity profiles over a large propagation distance without substantial diffraction and exhibit lateral bending during propagation1-5. This unique property has been exploited for micromanipulation of particles6, generation of plasma channels7 and guidance of plasmonic waves8, but has not been explored for high-resolution optical microscopy. Here, we introduce a self-b...
