Fiber-optic spectroscopy leverages light-guiding technology for remote sensing, offering a robust solution for real-time data ...

Polarized optical contrast spectroscopy is a simple and non-destructive approach to characterize the crystalline anisotropy and orientation of two-dimensional materials. Here, we develop a 3D-printed ...

A team of researchers from the Keck School of Medicine of USC and California Institute of Technology (Caltech) have developed a potential new way to measure a person's stroke risk that is ...

An outstanding challenge for deployable quantum technologies is high-resolution laser spectroscopy at the specific wavelengths of ultranarrow transitions in atomic and solid-state quantum systems.

Researchers demonstrated that speckle contrast optical spectroscopy (SCOS) can be used for cuff-less blood pressure monitoring. The new system can acquire measurements from the wrist or finger.

Normal, physiologic, autoregulated blood flow to the brain is central to essentially all aspects of human health, and when it goes wrong, the results can be catastrophic. However, due to our thick ...

Polaritons are coupled excitations of electromagnetic waves with either charged particles or vibrations in the atomic lattice of a given material. They are widely used in nanophotonics because of ...

Figure 1. (a) Schematic diagram of the optical trapping-enhanced SERS optofluidic detection system; (b) effect of the single-beam optical trap module switch state on AgNPs aggregation; (c1) and (c2) ...

A machine learning model has been developed that makes optical spectroscopy data easier and quicker to interpret. Researchers from Rice University (TX, USA) have developed a new machine learning ...

Researchers present the integration of a detector system and a polaritonic platform in the same 2D material, enabling for the first time the detection of 2D polaritonic nanoresonators with spectral ...
