Lateral resolution enhancement with standing evanescent waves

the lateral resolution Dr of conventional microscopy is given approximately by Dr l e 2NA l e 2 where l e is the emission wavelength and NA is the numerical aperture of the imaging optics Many techniques such as confocal and 4 pi microscopy have attained Dr l e 3 (Ref 1; p 48 Ref 2) Addition-ally atomic scale resolution has been achieved in

How is lateral resolution achieved in a widefield fluorescence microscope?
Lateral resolution that exceeds the classical diffraction limit by a factor of two is achieved by using spatially structured illumination in a wide‐field fluorescence microscope with strikingly increased clarity compared to both conventional and confocal microscopes. The resolution of an optical microscope is fundamentally limited by diffraction.
How can structured illumination improve the resolution of microscopy?
By adding a grating to the optical path, the structured illumination technique can be used to improve the resolution by a factor of 2.5 through two crucial modifications, namely, one to the pupil plane of the objective and the other to the demodulation procedure. Coherent super-resolution microscopy via laterally structured illumination.
What is the lateral resolution expected from the optical spectrum?
The simulation conditions are the same as in table 1. Then the lateral resolution expected from the aspect of the optical spectrum can be derived to be 78.5 nm based on formula (13). The simulation results of the discrete one and the continuous one are shown in figures 10 and 11, respectively.
Can spatially structured illumination microscopy double axial and lateral resolution?
This work describes how spatially structured illumination microscopy can be applied in three dimensions to double the axial as well as the lateral resolution, with true optical sectioning, and has produced the first light microscopy images of the synaptonemal complex in which the lateral elements are clearly resolved.

Definition

The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities. An example of this important concept is presented in the figure below (Figure 1), where point sources of light from a specimen appear as Airy diffraction ...

Properties

Resolution is a somewhat subjective value in optical microscopy because at high magnification, an image may appear unsharp but still be resolved to the maximum ability of the objective. Numerical aperture determines the resolving power of an objective, but the total resolution of the entire microscope optical train is also dependent upon the numeri...

Applications

Correct alignment of the microscope optical system is also of paramount importance to ensure maximum resolution. The substage condenser must be matched to the objective with respect to numerical aperture and adjustment of the aperture iris diaphragm for accurate light cone formation and specimen illumination. The wavelength spectrum of light used t...

Introduction

When the microscope is in perfect alignment and has the objectives appropriately matched with the substage condenser, then we can substitute the numerical aperture of the objective into equations (1) and (2), with the added result that equation (3) reduces to equation (2). An important fact to note is that magnification does not appear as a factor ...

Lateral resolution in an ideal optical microscope is limited to around 200 nm, whereas axial resolution is around 500 nm (examples of resolution limits are given below).

What is lateral resolution?

Lateral resolution is the image generated when the two structures lying side by side are perpendicular to the beam.
. This is directly related to the width of the ultrasound beam.
. Narrower the beam better is the resolution.
. The width of the beam is inversely related to the frequency.

What is lateral resolution in light microscope?

Lateral resolution in an ideal light microscope is limited to around 200 nm, whereas axial resolution is around 500 nm (for examples of resolution limits, please see below).

What determines lateral resolution?

Lateral resolution is roughly four times worse than axial resolution in ultrasound.
. It is primarily determined by the width of the ultrasound beam.
. Strategies to improve lateral resolution include increasing the number of lines per frame and setting multiple focal depths.

Why is axial resolution worse than lateral?

Typically, the lateral resolution is better than that of the axial resolution because the lateral resolution is inverse proportional to the numerical aperture of the system NA, while the axial resolution is inversely proportional to the squared numerical aperture NA2 (as derived below).

What is the lateral resolution of a light microscope?

Lateral resolution in an ideal light microscope is limited to around 200 nm, whereas axial resolution is around 500 nm (for examples of resolution limits, please see below). John William Strutt, 3rd Baron Rayleigh (1842-1919) was an English physicist and a prolific author.

What is axial resolution in optical microscopy?

Axial resolution in optical microscopy is even worse than lateral resolution (as outlined in Equation (2) ), on the order of 500 nanometers. When attempting to image highly convoluted features, such as cellular organelles, diffraction-limited resolution is manifested as poor axial sectioning capability and lowered contrast in the imaging plane.
