Phase Contrast and Differential Interference Contrast Microscopy01:26

Phase Contrast and Differential Interference Contrast Microscopy

8.2K
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...

Intensity Of Electromagnetic Waves

4.6K
The energy transport per unit area per unit time, or the Poynting vector, gives the energy flux of an electromagnetic wave at any specific time. For a plane electromagnetic wave with E0 and B0 as the peak electric and magnetic fields and traveling along the x-axis, the time-varying energy flux can be given by the following equation:

Infrared (IR) Spectroscopy: Overview

1.9K
When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

IR Spectroscopy: Hooke's Law Approximation of Molecular Vibration

1.4K
A covalently bonded heteronuclear diatomic molecule can be modeled as two vibrating masses connected by a spring. The vibrational frequency of the bond can be expressed using an equation derived from Hooke's law, which describes how the force applied to stretch or compress a spring is proportional to the displacement of the spring. In this case, the atoms behave like masses, and the bond acts like a spring.
According to Hooke's law, the vibrational frequency is directly proportional to...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

13.4K
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,...

Atomic Emission Spectroscopy: Interference01:30

Atomic Emission Spectroscopy: Interference

232
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Area of Science:

  • Optics and Photonics
  • Quantum Information Science

Background:

  • Traditional holography requires phase-stable light sources for interference.
  • Intensity interferometry, pioneered by Hanbury Brown and Twiss, measures intensity correlations of independent light sources.

Purpose of the Study:

  • To apply intensity interferometry principles to holography.
  • To develop a new method for wavefront reconstruction and hologram generation.

Main Methods:

  • Combining a signal beam with a reference beam.
  • Measuring intensity cross-correlations using a time-tagging single-photon camera.
  • Reconstructing the signal wavefront from the measured correlations.

Main Results:

  • Demonstrated successful wavefront reconstruction in both intensity and phase.
  • Showcased the technique with classical and quantum light, including single photons.
  • Confirmed that signal and reference beams do not require phase stability or common origin.

Conclusions:

  • Intensity interferometry provides a novel approach to holography.
  • This method enables holography of self-luminous or remote objects using a local reference.
  • Opens new avenues for advanced holography applications.
