Phase Contrast and Differential Interference Contrast Microscopy01:26

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...
Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...
Propagation of Uncertainty from Systematic Error01:10

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this particular...
Time and frequency -Domain Interpretation of Phase-lag Control01:21

Time and frequency -Domain Interpretation of Phase-lag Control

Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any finite,...

Area of Science:

  • Optical Metrology
  • Interferometry

Background:

  • Phase shifters in interferometers are prone to translational and tilt-shift errors.
  • These errors lead to nonlinear phase-measurement inaccuracies across pixels within an interferogram.

Purpose of the Study:

  • To develop a novel algorithm for phase-stepping interferometers.
  • To create an algorithm that is immune to both translational and tilt-shift errors in phase shifters.

Main Methods:

  • A new algorithm is presented that defines a phase-shift plane.
  • A first-order Taylor series expansion is used to approximate nonlinear equations for the phase-shift plane.
  • Iterative application of the algorithm ensures accuracy.

Main Results:

  • Computer simulations demonstrate complete compensation for phase-measurement errors.
  • The algorithm effectively corrects errors arising from both translational and tilt-shift errors.
  • Successful compensation was achieved even with tilt-shift errors up to 1%.

Conclusions:

  • The proposed algorithm offers a robust solution for phase error compensation in phase-stepping interferometry.
  • This method significantly enhances the accuracy of phase measurements by mitigating shifter-induced errors.
