    Abstract:

    The index-modulation evolution of a positive photoresist material was measured during the holographic exposure of sinusoidal patterns. The exposures were performed in a stabilized holographic setup that permits easy changes in the period. The results show the lowering of the recorded index modulation when the period decreases.

    Super-resolution Fluorescence Microscopy

    Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.
