Moiré Fringes Produced by a Point Projection X-ray Microscope
Summary
Soft X-rays passing through crossed gratings create Moiré fringes. These patterns may also arise from fibrillate structures in cellulosic materials, acting as natural diffraction gratings.
Area of Science:
- Physics
- Materials Science
- Biophysics
Background:
- Moiré fringes are interference patterns formed when two similar patterns are superimposed.
- Diffraction gratings are optical components with periodic structures that diffract light.
Purpose of the Study:
- To demonstrate Moiré fringe formation using soft X-rays and crossed gratings.
- To explore the potential of Moiré fringes in analyzing biological structures.
Main Methods:
- Soft X-ray transmission through fine wire mesh crossed gratings.
- Analysis of radio-micrographs of oriented cellulosic structures.
Main Results:
- Moiré fringes were successfully produced using soft X-rays and crossed gratings.
- Observed band patterns in radio-micrographs suggest Moiré fringe formation in cellulosic structures.
Conclusions:
- Soft X-ray diffraction through gratings is a viable method for generating Moiré fringes.
- Fibrillate structures in cellulosic materials may act as natural diffraction gratings, producing observable Moiré patterns.

25.6K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

11.0K
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.

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...

12.1K
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...

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...
