NIST Researchers Solve the Mystery of Degrading Sunlight Detectors

More than 150 years ago, the Sun blasted Earth with a massive cloud of hot charged particles. This plasma blob generated a magnetic storm on Earth that caused sparks to leap out of telegraph equipment and even started a few fires.

Chromasens Line-Scan Camera Helps Increase Manufacturing Yield with Faster, More Cost-Effective Inspections

Chromasens has broadened its line of allPIXA cameras with the new allPIXA evo 8K line-scan color camera. Designed for machine vision, the camera features a GigE Vision 2.0 compliant, dual 10 GigE interface combined with a CMOS sensor consisting of 16 lines of 8 K resolution (16 x 8192 5µm pixels). Each of the 16 lines may be independently controlled and allow for different read out modes. Full-color RGB image capture at line rates up to 3 x 90 kHz help to increase manufacturing yields while saving money with the cost-effective 10 GigE interface.

Study Advances the Understanding of Optical Fano Resonances

In 1961, physicist Ugo Fano provided the first theoretical explanation to an anomalous asymmetry observed in the spectral profiles of noble gases. He put forth an impactful interpretation of this phenomenon, now called "Fano resonance," stating that if a discrete excited state of a system falls within the energy range of a continuum of other possible states, these two can interfere with each other and give rise to abnormal peaks and dips in the system's frequency response.
