By using extreme numerical-aperture solid-immersion microscopy at 1553nm we demonstrate, under certain circumstances, polarization-sensitive imaging with resolution values approaching 100nm which substantially surpass the classical scalar diffraction-limit embodied by Sparrow’s resolution criterion.
Multiple image planes in a multiphoton microscope are acquired simultaneously through novel photon counting electronics and previous scaling limitations are overcome by a new Yb:KGW femtosecond oscillator laser design.
We demonstrate optical super-resolution by using custom obscuration apertures and polarization effects to manipulate the pupil-function and focal-plane point-spread-function in a two-photon microscope used for semiconductor flip-chip imaging. Experimental results suggest sub-100nm performance.
Conventional second-harmonic-generation anisotropy of collagen is modeled with cylindrical symmetry. We demonstrated that with thin fibrils, trigonal symmetry of constituent triple-helix molecules dominates the anisotropy, but it converged into cylindrical symmetry with thicker fibrils.
We demonstrate second-harmonic-generation (SHG) microscopic imaging on the polyhedral inclusion bodies (PIB) of nucleopolyhedrovirus in living cells. Due to a body-centeredcubic arrangement of polyhedrin trimers, these PIBs generate SHG with polarization anisotropy.
With miniaturized tube lenses and two-dimensional asynchronous scanning of the microelectro-mechanical-system mirror, we demonstrated a 24Hz frame-rate miniaturized two-photon fluorescence/second-harmonic-generation microscope system. Sub-micron transverse resolution of sectioning images can be achieved.
