Sentence examples for diffraction limitation from inspiring English sources

In the paper, we will report a kind of nanopillar array with a pillar diameter much smaller than Abbe's diffraction limitation by visible CW laser direct lithography technology.

Since the positive tone photoresist was applied in this work, a kind of nanopillar structure, whose diameter is far below diffraction limitation, could be obtained in the center of the donut-shaped pattern with appropriate input laser power.

Surface plasmon polaritons (SPPs) [21], elementary excitations coupled by photons and free-electron oscillations at an interface between a metal and a dielectric, are regarded as a promising physical mechanism to circumvent the diffraction limitation and to advance the miniaturization of the devices.

To improve the axial resolution near the diffraction limitation, using patterned illumination such as structured light and HiLo [ 13– 16] to eliminate the background noise and achieve optical sectioning is a reliable approach.

Currently, the lateral and axial spatial resolutions of TFMPEM are restricted by the diffraction limitation and the confined excitation volume to within a few hundred nanometers and few microns, respectively.

However, there are many approaches [ 18], to overcome the diffraction limitation and achieve superior lateral resolution, including photoactivation localization microscopy (PALM /stochastic optical reconstruction microscopy (STORM) [ 5, 19– 21], super-resolution optical fluctuation imaging (SOFI) [ 22, 23], and (nonlinear) structured-illumination microscopy (SIM/NSIM) [ 24– 28].

This allowed evaluating problems due to diffraction limitations and discretization introduced by the finite pixel size of the LCOS.

This will avoid possible ambiguity that may be imposed due to diffraction limitations (~250-300 nm) posed by light microscopy [ 2- 5].

These techniques utilize the on-off switching of fluorescent probes to ensure that each active fluorophore is isolated beyond the range of diffraction-limitation and ultimately build a high-resolution image from the precise and accurate positions of many single fluorophores (Deschout et al., 2014).

However, one of the key limitations of IR absorption spectroscopy is the diffraction limit, which is the primary experimental challenge for well resolved spatial IR imaging [ 1].

While the work of Groves and others in recent years has demonstrated the importance of protein and lipid spatial organization within cellular membranes, details as to how spatial organization is tied to function are scarce primarily because of the limitations of optical microscopy at length scales below the 250 nanometer diffraction limit.
