It can be used to achieve the diffraction limit based on the size of the low cost disk, rather than the high cost telescope mirror. One can envision affordable telescopes that could provide 7 ...

Experimental results have demonstrated that the diffraction-limited resolution barrier can be broken by a factor of 3. Consequently, the highest image resolution of 310 nm is achieved for the ...

Sub-diffraction Optical Writing Information Bits: Towards a High-Capacity Optical Disk for Big Data. March 1, 2021 – The total amount of data generated worldwide is expected to reach 175 ZB ...

Diffraction is a classic optical phenomenon accounting for light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The ...

Instead, by 3D printing onto an existing diffraction grating, the print can pick up the texture on its base layer. It’s a great way to add iridescence and shine to a print.

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary.

For the realization of 3D deep sub-diffraction OBL with nanometre feature size and feature resolution, three two-photon photoinitiators, BDEP, BDMA and BDCC were introduced into the formulation 9.

Laser diffraction needs a smaller representative sample when compared to sieving. However, it can also use larger samples. For a dry-dispersed laser diffraction experiment, the sample size ranges ...

With the latest laser-diffraction instrumentation, dry-powder dispersion can be applied to materials in the particle-size range 0.1 to 3500 microns. The widest possible use of dry dispersion maximizes ...
