Demonstration of an imaging system that can capture high-resolution 3D fluorescent images of biological speciments without the need for any moving parts.
The idea of using quantum optics to protect the transmission of sensitive data is becoming a commercial reality and starting to be deployed. Duncan Graham-Rowe takes a look at recent progress in quantum cryptography.
The demonstration of a laboratory-scale, fully coherent extreme-UV laser opens up a whole plethora of applications in ultrashort-wavelength imaging, microscopy and the probing of matter.
Non-reciprocal optical phenomena — effects that depend on the direction of light propagation — are rare. Researchers have now observed non-reciprocal material modification when moving a beam of ultrashort light pulses through a lithium niobate crystal.
Diffuse scattering can prevent high-resolution imaging in thick biological media. Researchers have now shown that such scattering can be completely cancelled by optical phase conjugation, opening the path to a new generation of medical imaging techniques.
Sensitive optical experiments and high-resolution microscopes often need to be mounted on vibration-control platforms to avoid unwanted disturbances to measurements. Neil Savage describes a selection of products designed for the task.
