What is Lensless Holographic Microscopy?
- https://www.azooptics.com/Article.aspx?ArticleID=2161
- A new lensless holographic microscopy technique promises high-quality imaging and analysis of biological samples without the need for lenses and could transform access to healthcare worldwide.
Multi-angle lensless digital holography for depth resolved …
- https://www.ncbi.nlm.nih.gov/sites/ppmc/articles/PMC2898907/
- A multi-angle lensfree holographic imaging platform that can accurately characterize both the axial and lateral positions of cells located within multi-layered micro-channels is introduced. In this platform, lensfree digital holograms of the micro-objects ...
Lensless Stokes holography with the Hanbury Brown …
- https://pubmed.ncbi.nlm.nih.gov/29716011/
- In this paper, we propose and experimentally demonstrate the Stokes holography with the Hanbury Brown-Twiss (HBT) interferometer. We also propose and implement a lensless Fourier configuration for the Stokes holography. This permits us to reconstruct the wavefront from the GSPs at any arbitrary distance from the scattering plane.
Holography is not lensless photography. - Holographyforum.org ...

- Some sources allege holography as being a "lensless photography." I disagree, for the following reason. In conventional photography, there is a light source, an object to be filmed, a lens, then the film the image is focused on--in that order. In holography, the sequence may be different, but the components are the same.
Optical refractometry using lensless holography and …

- Based on the Gabor holography, the lensless digital holographic microscopy has the advantages of light weight and low cost. It has developed rapidly and received attention in …
Lensless Photography : 9 Steps - Instructables
- https://www.instructables.com/Lensless-Photography/
- Step 1: Building a Lensless Adapter. A lensless adapter will protect the camera's inner components from contamination. This method uses an old lens and a UV filter. You can find a lens for cheap listed as "For parts or not working". Just …
Lensless digital holography with diffuse illumination …
- https://opg.optica.org/oe/abstract.cfm?uri=oe-19-25-25113
- Compared to standard inline holography the diffuse sample illumination improves the axial sectioning capability by increasing the effective numerical aperture in the illumination path, and it suppresses the undesired twin images. ... and Monika Ritsch-Marte, "Lensless digital holography with diffuse illumination through a pseudo-random phase ...
