Traditional objective lenses in modern microscopy, based on the refraction of light, are
restricted by the Rayleigh diffraction limit. The existing methods to overcome this limit can be …

Imaging cellular and extracellular structures and processes in situ and in vivo is highly
desired for the understanding and diagnosis of human diseases. High resolution optical …

Several image-based biomedical diagnoses require high-resolution imaging capabilities at
large spatial scales. However, conventional microscopes exhibit an inherent trade-off …

We address numerical dispersion compensation based on the use of the fractional Fourier
transform (FrFT). The FrFT provides a new fundamental perspective on the nature and role …

We introduce a cost-effective and easily implementable scan unit that converts any camera-
based microscope with optical sectioning capability into a multi-angle projection imaging …

We present a novel design approach for a binary phase mask with depth-of-focus (DoF)
extension ability. Our method considers that the binarized version of an axisymmetric …

We proposed a method to design a ternary optical element in order to achieve a needle of
super-resolution longitudinally polarized beam with ultra-long depth of focus, and obtained a …

This work presents a long-range and extended depth-of-focus optical coherence
tomography (OCT) system using a Bessel-like beam (BLB) as a visual feedback system …

We present a beam splitter mask that can be easily added to a multiphoton raster scanning
microscope to extend the depth of focus five-fold at a small loss in lateral resolution. The …

Binary phase filters (BPFs) form a special class of optical structure characterized by their
distinct concentric rings of alternating 0-π phases. Once placed in the pupil plane of a …
