Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Super-resolution Fluorescence Microscopy

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...

Area of Science:

Acoustic imaging
Geophysical exploration
Signal processing

Background:

The acoustic image source method simulates reverberation and characterizes seafloor sound-speed structure.
Detecting image sources via imaging provides environmental information.

Purpose of the Study:

To utilize image source detection for removing plane interface reflections from acoustic signals.
To perform enhanced imaging using the reflection-filtered signal.

Main Methods:

Detection of acoustic image sources.
Signal filtering to remove reflections from plane interfaces.
Imaging with the filtered signal to highlight scatterers.

Main Results:

The imaging process effectively highlights scatterers due to distinct wavefront shapes compared to plane interfaces.
