Three-dimensional fluorescent microscopy via simultaneous illumination and detection at multiple planes. [PDF]

, 2016
The conventional optical microscope is an inherently two-dimensional (2D) imaging tool. The objective lens, eyepiece and image sensor are all designed to capture light emitted from a 2D 'object plane'.

Label-free deeply subwavelength optical microscopy

Applied Physics Letters, 2020
We report the experimental demonstration of deeply subwavelength far-field optical microscopy of unlabeled samples. We beat the ∼λ/2 diffraction limit of conventional optical microscopy several times over by recording the intensity pattern of coherent ...

Interferometric phase-dispersion microscopy [PDF]

, 2000
We describe a new scanning microscopy technique, phase-dispersion microscopy (PDM). The technique is based on measuring the phase difference between the fundamental and the second-harmonic light in a novel interferometer.

Exploiting speckle correlations to improve the resolution of wide-field fluorescence microscopy [PDF]

, 2014
Fluorescence microscopy is indispensable in nanoscience and biological sciences. The versatility of labeling target structures with fluorescent dyes permits to visualize structure and function at a subcellular resolution with a wide field of view. Due to

Optical Flow on Evolving Surfaces with an Application to the Analysis of 4D Microscopy Data [PDF]

, 2013
We extend the concept of optical flow to a dynamic non-Euclidean setting. Optical flow is traditionally computed from a sequence of flat images. It is the purpose of this paper to introduce variational motion estimation for images that are defined on an ...

Second-order Nonlinear Optical Microscopy of Spider Silk [PDF]

, 2017
Asymmetric $\rm \beta$-sheet protein structures in spider silk should induce nonlinear optical interaction such as second harmonic generation (SHG) which is experimentally observed for a radial line and dragline spider silk by using an imaging ...
