Imaging Biological Samples with Optical Microscopy

4.6K
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...

NMR Spectrometers: Resolution and Error Correction

679
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Super-resolution Fluorescence Microscopy

6.9K
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...

    Summary
    This summary is machine-generated.

    Imaging systems with off-axis Seidel aberrations offer better resolution for object details than diffraction-limited systems. This is due to increased sensitivity and Fisher information, improving image quality for various photon statistics.

    Area of Science:

    • Optical Engineering
    • Image Science

    Background:

    • Diffraction-limited systems set the theoretical resolution limit.
    • Seidel aberrations are traditionally considered detrimental to image quality.

    Purpose of the Study:

    • To investigate the impact of off-axis Seidel aberrations on imaging system resolution.
    • To quantify the information content in systems with aberrations.

    Main Methods:

    • Theoretical analysis of imaging systems incorporating off-axis Seidel aberrations.
    • Fisher information calculations for object intensity estimation.
    • Evaluation under Poisson and additive Gaussian photon noise models.

    Main Results:

    • Systems with off-axis Seidel aberrations demonstrate superior resolution compared to diffraction-limited systems.
    • Increased Fisher information observed due to enhanced sensitivity (shift variance).
    • Resolution improvement is consistent across different photon statistics.

    Conclusions:

    • Off-axis Seidel aberrations can enhance, rather than solely degrade, imaging system performance.
    • Aberrations improve the ability to distinguish similar object scenes.
    • This finding challenges conventional understanding of aberration effects in imaging.
