Quantum plasmonic biosensors enable self-illumination for real-time, label-free diagnostics with scalable point-of-care applications.

The new €3.5m GASPOF (Pervasive Gas Sensing Using Optical Fibres) project, funded by the European Commission and supported by ...

When the light beam through the tube is blocked by an air bubble within the tube, the threshold is met, and the sensor’s output is switched over accordingly. This post describes the design concept of ...

A new sensor could help keep that from happening, using scattered light. Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life ...

Scientists at EPFL have created a revolutionary biosensor that doesn't need a light source—it makes its own glow using ...

Elementary’s VisionStream AI is used to inspect Yamaha’s manufacturing lines in real time, bringing speed and simplicity to quality control ...

For each design, the model assesses sensor response as a function of fiber size, distance, NA, and tilt angle. Experiments used 660 nm laser light, precision movement equipment, detectors, and ...

The system can detect enemy submarines, drones, and surface vessels from up to 150km away — without revealing its own ...

This new approach uses carefully engineered light pulses as atomic mirrors to cut noise and sharpen quantum measurements.

Optical fingerprint scanners: The most common on smartphones. ... Optical fingerprint sensors shine a bright light through your phone's display to capture a 2D image of your finger.
