Photon sieve - Wikipedia
- https://en.wikipedia.org/wiki/Photon_sieve
- A photon sieve is a device for focusing light using diffraction and interference.It consists of a flat sheet of material full of pinholes that are arranged in a pattern which is similar to the rings in a Fresnel zone plate, but a sieve brings light to much sharper focus than a zone plate.The sieve concept, first developed in 2001, is versatile because the characteristics of the focusing ...
The Photon Sieve Could Revolutionize Optics - Universe …

- The photon sieve operates on the same basic principles, but with a slightly more sophisticated twist. Instead of thin openings (i.e. Fresnel zones), …
Photon Sieve
- http://www.photonsieve.de/
- An optical element, based on the simple concept of an array of pinholes, (a photon sieve) exploits the monochromaticity and coherence of light from a free-electron laser to focus soft X-rays with unprecedented sharpness. The combination of an excellent focus with extreme flux will provide new opportunities for high-resolution X-ray microscopy ...

- The photon sieve is a thin film of titanium filled with randomly oriented pinholes. By placing the photon sieve close to a transmissive LCD panel, the diffraction angle of the light field can be considerably enhanced. The actual 3D holographic display, and an electron microscope image of the nonperiodic pinholes. ...
Photon sieve: the future of ultralight space telescopes?

- Etched into a silicon wafer, the photon sieve shown below is a lab test device developed at NASA’s Goddard Space Flight Center (Greenbelt, MD); it is a miniature prototype of a future 1-m-diameter photon sieve that could one day be used in space to image the Sun at UV wavelengths. While this photon sieve brings red laser light to a pinpoint ...
Photon-sieve lithography - PubMed
- https://pubmed.ncbi.nlm.nih.gov/15717565/
- We present the first lithography results that use high-numerical-aperture photon sieves as focusing elements in a scanning-optical-beam-lithography system [J. Vac. Sci. Technol. B 21, 2810 (2003)]. Photon sieves are novel optical elements that offer the advantages of higher resolution and improved i …

- This ‘photon sieve’ could one day enable dynamic 3D images to be viewed on mobile devices. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in collaboration with SAIT Samsung Electronics placed an array of sub-micron apertures over a commercial LCD panel illuminated from behind with a laser. Light is diffracted ...

How to Make a Zone Plate, Photon Sieve or Pinhole Sieve
- https://pinholeday.org/docs/Zone_Plate_and_Sieves/
- Using a text editor, like Microsoft's Notepad or equivalent, open the corresponding PostScript file (zoneplate.ps, pinholesieve.ps or photonsieve.ps). Change the parameter as indicated in the Postscript code. For instance, to change the focal length of the "lens" to 80mm, you will change the number in the following line: /F 75 def % change the ...
