Extended resolution fluorescence microscopy.
Fluorescence microscopy is an essential tool of modern biology, but, like all forms of optical imaging, it is subject to physical limits on its resolving power. In recent years, several exciting techniques have been introduced to exceed these limits, including standing wave microscopy, 4Pi confocal microscopy, I5M and structured illumination microscopy. Several such techniques have been definit...
متن کاملmhFLIM: resolution of heterogeneous fluorescence decays in widefield lifetime microscopy.
Frequency-domain fluorescence lifetime imaging microscopy (FD-FLIM) is a fast and accurate way of measuring fluorescence lifetimes in widefield microscopy. However, the resolution of multiple exponential fluorescence decays has remained beyond the reach of most practical FD-FLIM systems. In this paper we describe the implementation of FD-FLIM using a 40 MHz pulse train derived from a superconti...
متن کاملHigh Resolution Quantitative Angle-Scanning Widefield Surface Plasmon Microscopy
We describe the construction of a prismless widefield surface plasmon microscope; this has been applied to imaging of the interactions of protein and antibodies in aqueous media. The illumination angle of spatially incoherent diffuse laser illumination was controlled with an amplitude spatial light modulator placed in a conjugate back focal plane to allow dynamic control of the illumination ang...
متن کاملWide-field extended-resolution fluorescence microscopy with standing surface-plasmon-resonance waves.
The resolution of conventional surface-plasmon-resonance (SPR) imaging has been limited by the diffraction nature of light. A wide-field extended-resolution optical imaging technique, standing-wave SPR fluorescence (SW-SPRF) microscopy, has been developed. Based on evanescent SPR standing waves, SW-SPRF provides lateral resolution approaching 100 nm and offers the advantages of significant sign...
متن کاملWidefield fluorescence microscopy with sensor-based conjugate adaptive optics using oblique back illumination.
We describe a wavefront sensor strategy for the implementation of adaptive optics (AO) in microscope applications involving thick, scattering media. The strategy is based on the exploitation of multiple scattering to provide oblique back illumination of the wavefront-sensor focal plane, enabling a simple and direct measurement of the flux-density tilt angles caused by aberrations at this plane....
