Interference and Diffraction02:18

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

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...
Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Imaging Biological Samples with Optical Microscopy01:18

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...
Distance Corrections01:15

Distance Corrections

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

    Area of Science:

    • Optical physics
    • Biomedical imaging
    • Metrology

    Background:

    • Dispersive samples cause wavelength-dependent phase distortion, degrading depth resolution in high-resolution OCT with broadband sources.
    • Current dispersion compensation methods, like using dispersive materials, are difficult to implement in a depth-dependent manner.

    Purpose of the Study:

    • To present a novel numerical dispersion compensation technique for Partial Coherence Interferometry (PCI) and Optical Coherence Tomography (OCT).
    • To enable depth-dependent dispersion compensation that can be applied post-acquisition.

    Main Methods:

    • A numerical correlation technique using a depth-variant kernel is employed to compensate for dispersion.
    • The method is applied a posteriori to depth scan signals.

    Main Results:

    • The technique provides depth-dependent dispersion compensation.
    • Examples demonstrate successful dispersion compensation in depth scan signals from microscope cover glasses, improving resolution.

    Conclusions:

    • Numerical dispersion compensation offers an effective post-acquisition solution for improving depth resolution in OCT and PCI.
    • This method overcomes the limitations of traditional depth-independent dispersion balancing techniques.
