In recent years, vortex beams with orbital angular momentum (OAM) have attracted more
and more attention. The wavefront of the OAM beams is helical, the intensity at the center of …

Optical methods of super-resolution microscopy, such as confocal microscopy, structured
illumination, nonlinear microscopy, and image scanning microscopy are reviewed. These …

High‐charge optical vortices, every photon of which carries an orbital angular momentum
with a large quantum number, are ideal sources for testing macroscopic quantum …

Point spread function (PSF) engineering by an emitter's response can code higher‐spatial‐
frequency information of an image for microscopy to achieve super‐resolution. However …

Biological research increasingly demands the use of non-invasive and ultra-sensitive
imaging techniques. The Airyscan technology was recently developed to bridge the gap …

We demonstrate that the spatial resolution in confocal laser scanning microscopy is
remarkably improved by simple image subtraction between images acquired by higher …

Ultrasound localization microscopy (ULM) demonstrates great potential for visualization of
tissue microvasculature at depth with high spatial resolution. The success of ULM heavily …

For decades, the spatial resolution of conventional far‐field optical imaging has been
constrained due to the diffraction limit. The emergence of optical super‐resolution imaging …

Laser scanning microscopy is limited in lateral resolution by the diffraction of light. We show
that we can obtain twenty percent improvement in the resolution of confocal microscopy …

Image enhancement techniques (such as edge and contrast enhancement) are essential for
many imaging applications. In incoherent holography techniques such as Fresnel …
