Transmission Electron Microscopy

Transmission Electron Microscopy

In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400 keV in...

Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

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,...

Immunofluorescence Microscopy

Immunofluorescence Microscopy

A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.

Area of Science:

Optics and Photonics
Image Transmission
Holography

Background:

Multimode optical fibers suffer from modal dispersion, leading to image distortion.
Phase conjugation offers a potential solution for wavefront correction in optical systems.

Purpose of the Study:

To achieve distortion-free, one-way transmission of multipixel images through multimode optical fibers.
To implement a holographic method for individual pixel wavefront correction.

Main Methods:

Utilizing the phase-conjugation principle for image transmission.
Superposing distortion-compensating holograms for each image pixel onto a photoplate.
Employing holographically generated reference beams with varying incidence angles for pixel-specific wavefront correction.

Main Results:

Successful one-way transmission of multipixel images through a multimode optical fiber.
Experimental demonstration of transmitting images with up to 25 pixels.
Effective wavefront correction for each pixel without inter-pixel interference.

Conclusions:

The phase-conjugation principle combined with tailored holography enables high-fidelity image transmission in multimode fibers.
This technique overcomes the limitations of modal dispersion for image-carrying optical fibers.
The method is scalable for transmitting more complex images.
