Imaging Biological Samples with Optical Microscopy

Imaging Biological Samples with Optical Microscopy

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

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,...

Phase Contrast and Differential Interference Contrast Microscopy

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Three-Dimensional Microscopy in Microbiology

Three-Dimensional Microscopy in Microbiology

Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...

Area of Science:

Optical Physics
Biomedical Imaging
Interferometry

Background:

Conventional spectral domain interferometry (SDI) requires data linearization, limiting its application in 3D optical coherence tomography (OCT).
Existing SDI methods for OCT cannot produce direct en-face cross-sections, hindering comprehensive 3D visualization.
These limitations restrict the speed and cost-effectiveness of high-resolution 3D OCT imaging.

Purpose of the Study:

To introduce a novel SDI method, Master-Slave Interferometry (MSI), that overcomes the disadvantages of conventional SDI techniques.
To enable direct en-face cuts and parallel processing capabilities in OCT systems.
To reduce the cost and increase the speed of producing en-face OCT images for advanced applications.

Main Methods:

Developed a novel Master-Slave Interferometry (MSI) approach, replacing the serial signal acquisition of conventional SDI.
Implemented a slave interferometer to acquire signals based on optical path difference (OPD) values determined by a master interferometer.
Designed an MSI setup that generates multiple signals, one for each OPD point within the investigated object.

Main Results:

The MSI method eliminates the need for data linearization, simplifying OCT system processing.
MSI enables direct en-face OCT imaging, overcoming a key limitation of conventional SDI.
The parallel nature of MSI allows for parallel sensing and signal processing, enhancing 3D OCT capabilities.

Conclusions:

The novel MSI method significantly advances SDI techniques for OCT applications.
MSI facilitates high-resolution medical imaging and microscopy of biosamples through improved 3D visualization.
This approach offers potential for lower-cost OCT systems and faster en-face image generation compared to conventional SDI.
