Quantitative polarized light microscopy
Journal of Microscopy, 2003SummaryWe 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 ...

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 ...

Multiphoton Polarization Microscopy
1998Abstract By analyzing the polarization or anisotropy using steady-state or time-resolved methods, orientation information or dynamics of molecular systems can be investigated (Lakowicz, 1999). The natural extension of polarization spectroscopy is to implement polarizationresolved analysis in conjunction with optical microscopy.

Polarization effects in 4Pi microscopy
Micron, 2011The 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 resolved second harmonic microscopy
Methods, 2017Second harmonic (SH) microscopy has proven to be a powerful imaging modality over the past years due to its intrinsic advantages as a multiphoton process with endogenous contrast specificity, which allows pinhole-less optical sectioning, non-invasive observation, deep tissue penetration, and the possibility of easier signal detection at visible ...

FRET by Fluorescence Polarization Microscopy
2008The 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

Differential Polarization Microscopy
1991Differential polarization microscopy is the name given to a group of microscopic techniques that create images using changes in the polarization of light or changes in the amount of polarized light (linear or circular) transmitted or scattered by an object. This will be made clearer by first examining several better-known microscopic techniques.

Spin-polarized scanning tunnelling microscopy
Reports on Progress in Physics, 2003The recent experimental progress in spin-polarized scanning tunnelling microscopy (SP-STM)—a magnetically sensitive imaging technique with ultra-high resolution—is reviewed. The basics of spin-polarized electron tunnelling are introduced as they have been investigated in planar tunnel junctions for different electrode materials, i.e.

The waves in a beam of ordinary light vibrate in all directions transverse to the direction of propagation. However, under certain conditions some directions of vibration are eliminated or rotated so that the vibrations occur either in a single plane or in a pair of planes: in the former case we say that the light is plane polarized and in the latter ...

The optical microscope is used extensively in pharmaceutical development with the primary application being solid-state analysis. The applications range from simple images of drug substance to illustrate particle size and shape to full optical crystallography. The range of utility of the microscope is considerably extended by the use of polarized light
