Holographic Technique Uses Deep Learning to Increase Accuracy, Improve Microscopy
Deep learning, one of the key technologies behind advances in real-time speech recognition and automated image and video labeling, is being used to reconstruct holograms to form microscopic images of samples. Researchers are using a convolutional neural network-based method that is trained through deep learning to rapidly perform phase recovery and holographic image reconstruction.

Quantum Optics Lead to Spectroscopy Method for Measuring on FS Time Scale
Scientists have demonstrated a time-resolved spectroscopy technique that enables the study of very fast processes in samples on the femtosecond (fs) time scale without the need for an fs laser or a complex detection system. The method works by analyzing quantized light transmitted through a sample. It relies on single photons to study the interactions and processes occurring in the samples and ordinary lasers to produce the photons.

Coupling Perovskite to Nanophotonic Cavities for More Efficient Optoelectronics
Coupling Perovskite to Nanophotonic Cavities for More Efficient Optoelectronics
To boost the efficiency of perovskite as a light source for optoelectronics, researchers coupled lead halide perovskite nanocrystals to a nanophotonic cavity. The research team drop cast perovskite nanocrystals in a toluene solution onto a silicon nitride (SiN) cavity. They then excited the device with a pulsed laser, which led to photon emission from the nanocrystals.

Visible Light Controls Chemical Reaction Pathways, Could Be UV Alternative
Visible Light Controls Chemical Reaction Pathways, Could Be UV Alternative
A technique has been developed that modulates visible colored light, enabling it to control the reactions of chemical coupling agents needed to make industrial materials. Researchers showed that the modulation of the reactivity by light could be reversed, and that individually addressable reaction pathways could be repeatedly accessed.

BiOS 2018
BiOS 2018
January 27-29, 2018 - The Moscone Center - San Francisco United States
SPIE BiOS 2018, part of SPIE Photonics West, encompasses clinical, translational and fundamental research and development in the field of biomedical optics and photonics. It provides a technical forum for reporting and learning about the latest research and development, as well as for launching new applications and technologies. This year BiOS will offer 2,400 papers and presentations on a range of topics that include biomedical optics, diagnostics and therapeutics, biophotonics, new imaging modalities, optical coherence tomography, neurophotonics, optogenetics, tissue optics and nano/biophotonics.
