Polarization effects in 4Pi microscopy

Micron, 2011
The effects of different apodization conditions and polarization distributions on imaging in 4Pi microscopy are discussed. Performance parameters are derived that allow the different implementations to be compared. 4Pi microscopy is mainly used because of its superior axial imaging performance, but it is shown that transverse resolution is also ...

Polarization Microscopy

Current Protocols in Cell Biology, 2002
AbstractThis unit provides an introduction to polarization microscopy, the optics involved, and practical considerations for observing submicroscopic structures. The unit also includes specific examples for visualization of microtubules in the mitotic spindle, chromatin within maturing spermatids, and the biocrystalline skeletal spicules in larval ...

FRET by Fluorescence Polarization Microscopy

2008
The widespread success in using genetically encoded fluorescent proteins (FPs) to track protein motion in living cells has led to extensive interest in measuring Förster resonance energy transfer (FRET) between two FPs of different colors. FRET occurs over distances less than 10-nm and can thus be used to detect protein-protein interactions and changes

Microscopy with Polarized Light

1978
The historic observation of double imaging by a highly birefringent crystal, such as that of calcite (see Chapter 1), can easily be repeated on an overhead projector. A small dot of black paper is pasted on the projector’s window near its center, then a cleavage rhombohedron of clear calcite is placed over the dot.

Quantitative polarized light microscopy

Journal of Microscopy, 2003
SummaryWe describe a simple modification to a confocal microscope, which analyses the state of polarization of light emerging from the specimen so as to permit quantitative polarized light microscopy to be performed. The system uses a novel form of rotating analyser which, together with lock‐in detection, permits images to be obtained where the image ...

Polarization conversion in confocal microscopy with radially polarized illumination

Optics Letters, 2009
The effects of using radially polarized illumination in a confocal microscope are discussed, and the introduction of a polarization mode converter into the detection optics of the microscope is proposed. We find that with such a configuration, bright-field imaging can be performed without losing the resolution advantage of radially polarized ...
