A newly developed technique uses a Bessel beam to extend the focus of optical coherence microscopy, allowing for a detailed imaging of large sections of the brain. Unlike traditional methods that ...

The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

PowerPhotonic, a developer and manufacturer of freeform, wafer-scale optics, based in Fife, UK, has this week been exhibiting and presenting an invited paper at SPIE Sensors and Imaging, in Amsterdam, ...

(a) Schematic of the PC-SRS microscope system for 3D chemical imaging. Inset drawings illustrate the ring-shaped pump beam and Gaussian Stokes beam on the SLM. (b) The distortion-corrected phase ...

Darwin Quiroz is exploring new frontiers in miniature lasers with major biomedical applications. When Quiroz first started working with optics as an undergraduate, he was developing atomic ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...
