Graphene allows lenses with night vision capability

The research group said they clip into graphene through the two lenses in the middle to produce a can capture any light from the visible to the infrared sensor. They have made ​​a prototype smaller than a fingernail, experts said, one day it will be embedded in the lens, night vision capability to provide soldiers and other people in need. University of Michigan Zhong Zhaohui (Zhaohui Zhong) said they tiered approach can be made ​​out of ultra-thin sensor. The associate professor of electronics and computer engineering, said: "We can make the whole design to achieve the slim effect we can put it on the lens cover, or are combined with the phone.."

Zhong Zhaohui build this prototype device has been "smaller than some of the pink fingernails," and it is easy to be scaled down. He said: "If we combine it with contact lenses or other wearable electronics, it will be able to expand your horizons as you interact with the surrounding environment provides an alternative way.." This device utilizes graphene "super sensor" feature. This material when exposed to photons (light), will be a strong influence. This will lead it into the so-called "hot carrier" scientists this effect can be measured, processed and converted into an image. The research team has discovered a new method that can graphene sandwiched between two lenses in the middle, to make it as sensitive as silicon CMOS image sensors used in commercial digital cameras.

The research group in the "Nature" magazine wrote: "The ultra-wideband photodetector, the graphene is a promising candidate material because it covers the entire infrared absorption spectrum to the far-infrared spectrum of this series we report here an ultra wideband graphene layer heterostructure photodetector design. this detector is a phototransistor, by a pair of stacked graphene monolayers composed of two separated by a tunnel junction-layer film in the optical illumination, hot carriers generated in the upper layer of the excitation light will pass through the tunnel along the lower, resulting in the charge accumulation gate, and generates the channel conductance of the strong optical selection effects. demonstration of the device at room temperature photoelectric control measure from visible to mid-infrared range.

British farmers invention can relieve motion sickness special sunglasses

Motion sickness often brings trouble to travel, but perhaps we should have a savior! According to Hong Kong's Wen Wei Po reported on May 6, Britain Norfolk farmer Flaxman invented a special sunglasses, which can interfere with visual signals through the 3D scene becomes 2D, signals the body to avoid confusion and to solve sickness discomfort.

Glasses named "Travel Shadows" (Travel Shades), while a solid color lenses, allowing wearers to move the eye can see only one side of sight, touch and exempt because the visual is not synchronized, the brain receives a signal differences caused by sickness vomiting sensation.

Glasses can be worn around inversion, which are readily convertible to cover the eyes. 53-year-old inventor Flaxman tried this product, car, boat were unharmed. With the invention of his debut TV show "Millionaire inventor", but also attracted many large chain pharmacies order.

Inner Mongolia Institute of Metrology regulate the development of optical industry

Which lasted two years, market research, feasibility studies, demonstration and trial run, recently presided over the drafting of the Inner Mongolia Autonomous Region Institute of Metrology local standards "glasses optometry industry quality management service standards" approved by the Municipal Quality Supervision Bureau official promulgation, thereby filling the autonomous eyewear industry is no standard blank. In recent years, the Inner Mongolia Autonomous Region in the glasses optometry, optician business enterprises and self-employed persons has developed rapidly, a significant increase in the number of optical shops so far has reached more than 1,400. But the local optical industry experience with technology, glasses assembly quality and service can not meet consumer demand.

Eyewear industry standardization is the basis for the development of modern service industry, glasses, introduced the "glasses industry optometric service quality management standard" standards for optical industry practitioners have the qualifications, test conditions, the production and fitting safety glasses should achieve quality requirements and technical service standards, etc. to give specific guidance and specifications. The standard specification for the autonomous glasses optometry industry market order, improve service quality and technical level, strengthen the supervision of optometry industry, optical industry and create a fair, just, and healthy development of the environment, safeguard the legitimate rights and interests of operators and consumers other aspects will play a positive role in promoting.

The difference between the polarizer and sunglasses

What is the difference and sunglasses polarizer is it ? The start of several concept, what is the polarizer ? What is the role of the polarizer is ? What is the connection of these two , what is the difference ? Here on these issues to make a detailed answer.
What is a polarizer ?
Polarizer is manufactured according to the principle of polarization of light . We know that when the sun projected on the road or water, direct irritation of the eyes , the eyes dazzle , fatigue, vision can not be sustained . Especially when you drive a car, outdoor recreational activities, not only affects our emotions work and play , and even affect our sense of the images and danger ; long withstand direct sunlight, but also lead to the rapid decline in vision , form of myopia , hyperopia, astigmatism or cataracts.
Effects polarizer is effectively excluded and filtered light scattering light. So that light can be on the right track for the transmission axis of the eye into visual images , making clear vision of nature . Principles like Venetian blinds , the light is adjusted to the light into the interior with natural scenery looks so soft and without glare .
Polarizer what effect?
Effects polarizer is effectively excluded and filtered light scattering light. So that light can be on the right track for the transmission axis of the eye into visual images , making clear vision of nature .
Polarized sunglasses is to use this feature to block harmful rays as sunlight to touch any object , whether due to natural reflection or refraction will generate harmful glare, polarized sunglasses can completely absorb these can cause glare and eye damage glare . Because polarized sunglasses with polarized light function, so that all can block out the harmful rays are not affected by visible light , can really achieve eye protection function.
