Digital resolution enhancement in surface plasmon microscopy

Resolution and sensitivity in surface plasmon microscopy and sensing

The use of surface plasmons on planar surfaces for the characterisation of those surfaces is analysed. In particular, analytic expressions are derived for the sensitivity of such characterisation to the variation of bulk refractive indices, and to the addition of thin dielectric layers on the plasmon supporting surface. Comparison between surface plasmon and dielectric waveguide techniques is m...

High 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...

Resolution enhancement techniques in microscopy

We survey the history of resolution enhancement techniques in microscopy and their impact on current research in biomedicine. Often these techniques are labeled superresolution, or enhanced resolution microscopy, or light-optical nanoscopy. First, we introduce the development of diffraction theory in its relation to enhanced resolution; then we explore the foundations of resolution as expounded...
