The Falcon Heavy payload fairing goes blue (da ba dee, da ba daa).

Researchers from the Moscow Institute of Physics and Technology and Lebedev Physical Institute of the Russian Academy of Sciences have designed and tested a prototype cathodoluminescent lamp for general lighting. The new lamp, which relies on the phenomenon of field emission, is more reliable, durable, and luminous than its analogues available worldwide. The development was reported in the Journal of Vacuum Science & Technology B.

While LED lamps have become commonplace, they are not the only clean and power-saving alternative to incandescent lamps. Since the 1980s, engineers around the world have been looking into the so-called cathodoluminescent lamps as another option for general lighting purposes.

Shown in figure 1, a lamp of this kind relies on the same principle that powered TV cathode-ray tubes: A negatively charged electrode, or cathode, at one end of a vacuum tube serves as an electron gun. A potential difference of up to 10 kilovolts accelerates the emitted electrons toward a flat positively charged phosphor-coated electrode—the anode—at the opposite end of the tube. This electron bombardment results in light.

Single-pixel cameras (SPC) are image capturing devices, which use only a single detector to collect information about the entire image, by making use of it.

Computer vision researchers report using special light sources and sensors to see around corners or through gauzy filters, letting them reconstruct the shapes of unseen objects.

The 21st Century version of the Kirlian camera is now called a GDV camera.

Biosensors can also be sprayed.

A new touchless world of biosensing is emerging, and its implications are unequivocal. What does this mean for wearables, telehealth, and research?

Rare, “rainbow” blanket octopuses were caught on camera off the coast of Romblon, Philippines.

Starting at the end of next year, some of Vienna’s walk-light push-buttons will be disappearing from the city’s pedestrian crossings. Instead, a new system will be trialled, that uses cameras and computers to visually detect when people wish to cross the road.

Francis Halzen, the lead scientist of the IceCube Neutrino Detector, explains how light sensors buried deep in the ice at the South Pole detected a neutrino that traveled four billion light-years.
