|Night vision technology has opened up a wide range of possibilities. Before the development of night vision Caris LeVert Nets Jersey , we could only see and observe objects those are visible to the naked eye, that too under light. Night vision enables us to see clearly in extreme low light conditions. With the help of a night vision device like monocular or binocular, you can clearly see a person standing hundreds of yards away on a dark moonless night with cloud in the sky. There is such advanced technology that might enable you to view objects even in pitch black condition. What is not visible to the naked eye even under light may be perceived with the help of heat sensing night vision devices.
Application of night vision
Night vision devices find application in a number of fields. One of the most important applications of night vision devices is in military activities, especially in the dark. High range monocular devices are often mounted on guns and rifles, which help in spotting and hitting targets under very low light. Night vision devices are also used by the military or law enforcement departments for the purpose of surveillance at night. There are strategically placed surveillance cameras those have night vision technology built in them. Night vision is also applicable to wild life observation and supervision. In the jungles Allen Crabbe Nets Jersey , a lot of activities occur nocturnally.
Different technologies used
Two distinct technologies are used in developing night vision devices. The first one is image enhancement process. A device that enables night vision captures a tiny amount of light reflected by objects under dimly lit conditions. This light passes through a series of plates like a photo cathode, a high voltage micro channel plate and finally a green phosphor screen. As it passes through these layers, the light gets amplified before reaching the observer’s eyes. An example of such a device is Night vision Goggles. The other method is called thermal imaging. The upper part of the infrared spectrum emitted by objects are captured and transformed into visible images by the device. The user can view and distinguish between objects in absolute darkness based on the heat they emit.
Digital night vision
Today, night vision technology has taken a new leap with the advent of digital technology. Devices with Night Vision Digital have a number of advantages over traditional analogue systems. Digital systems can handle light of any intensity. Analogue systems are not built to deal with bright lights. Video recording facilities are easily integrated with digital systems whereas, for traditional devices Timofey Mozgov Jersey , additional pieces of equipment are needed to be attached.
ENTEBBE, Uganda, July 25 (Xinhua) -- Building a highway through swamps can be a nightmare for some contractors, particularly in the era of heightened environment protection, but it has proven to be job not so difficult for a Chinese firm operating in Uganda.
The Chinese firm -- China Communications Construction Company (CCCC) -- has actually become a pacesetter in taking high environmental standards into consideration in the execution of the hard construction of a highway through a swamp -- which will be Uganda's first expressway.
The close-to-50 km road traverses several swamps Sean Kilpatrick Jersey , with one section of the road including a 1.5-km bridge, the longest in the country and in the east African region, according to experts.
The bridge, a highlight of the over 350-million-U.S.-dollar project, was built over a swamp which is a life line to Lake Victoria Rondae Hollis-Jefferson Jersey , Africa's largest and the world's second biggest fresh water body.
""We ensured that we do not cause environmental degradation and we have now achieved it,"" Li Jincheng, project manager of Kampala Entebbe Expressway, told Xinhua in a recent interview.
Experts have urged Uganda to implement sustainable development, warning that the country's ecosystem may be destroyed otherwise Nik Stauskas Jersey , which might lead to harsh climate change effects.
In the northern part of the country, another environmentally friendly project is being constructed by the Chinese along River Nile, the world's longest river.
The Karuma Hydro Power Plant, worth 1.4 billion dollars, will be the first hydropower station in Africa that is constructed underground Julius Erving Jersey , partly in efforts to minimize negative environmental impact on the river.
Besides building eco-friendly facilities, Chinese enterprises in the country have created a fund to help conserve Lake Victoria, encouraging all Chinese companies operating in Uganda to make contribution thereto.
For Chinese enterprises to continue making profits here, they need to maintain the environment today so that these resources are not depleted,Zhou Tianqi Jeremy Lin Jersey , chairman of the fund dubbed Save the Wild Fund was quoted by the Daily Monitor as saying last week.
The fund is partnering with local authorities in the region to lobby Chinese companies to join the efforts to support tree planting around the Lake. The first batch of 10,000 tree seedlings has already been dispatched.
Sustainable development and protection of the environment are both critical to the development of the country, said Zheng Zhuqiang, Chinese ambassador to Uganda, at a recent meeting on environmental protection Jarrett Allen Jersey , noting that Chinese enterprises are well cooperating with local authorities to ensure environmental protection.
Ugandan State Minister for Environment Mary Kitutu said that if Chinese set up their investments in the 23 industrial parks across the country, they would not face any problem regarding degradation of the fragile ecosystem.
The minister also urged Chinese investors to always follow the proper channels instead of using intermediaries who may fleece them resulting in the loss of their investment.
