A new method from University of Vienna researchers combines SR-SIM with electro-optic fluorescence lifetime imaging to achieve super-resolved imaging of cellular dynamics: https://bit.ly/3QiXnwF

The super-resolution microscopy technique demonstrated super-resolved multiplexed imaging of spectrally overlapping fluorophores, enhanced contrast due to optical sectioning, and environmental sensing at a spatial resolution of 156 nm.

New publication in Optica! Super-resolution structured illumination microscopy of cellular dynamics with fluorescence lifetime contrast

A new expands lidar sensing beyond distance and motion by mapping location, speed and material properties in a single measurement.

The system, which uses a coherent optical modem as the transmitter and receiver, captures millimeter-accurate distance, velocity and surface material while using eye-safe laser power.

This could lead to safer autonomous vehicles, more capable robots, better industrial inspection and sensing systems that work in poor visibility caused by glare, fog, or heavy rain.

research demonstrates polygonal spatiotemporal optical vortices wavepackets with a prescribed vortex structure https://bit.ly/4e7usEV

Overcoming limitations in STOV wavepackets, these new wavepackets open up opportunities for research and applications in optical communication, multiple-target particle manipulation and studying complicated quantum systems.

In recent work from ETH Zürich, TU München and the Universität Konstanz, a team discovered localisation transitions induced by temporal fluctuations in collective states of light supported by fast-gain .

By introducing temporal noise into the modulation of the laser cavity, the team created a fluctuating potential along a synthetic frequency lattice formed by the laser modes.

As the noise strength increases, the laser emission evolves through three distinct regimes: a broad spectrum, a Gaussian distribution and finally exponential localization.
