Successfully fabricated night vision goggles

After more than four years of hard work, scientists from the Institute of Physics and Electronics (Vietnam Institute of Science and Technology) have successfully researched and mastered the technology of manufacturing night vision devices using transducers. amplify modern generation photo.

(Photo: TTO) Research, development and manufacture of lenses of general optoelectronic devices and night vision goggles require the coordination of many high-tech science fields: optical, optoelectronic, laser, physical thin film, precision mechanics, microelectronics, math-informatics, automatic control, image processing and identification . In the world, not all developed industrial countries can do it.

The proactive research on manufacturing night vision goggles is not only economically meaningful as a significant saving of foreign currency for design and technology imports, reducing product costs but also diversifying strains night vision goggles and promote many other industries to develop. Because, if we use a third-generation image amplification receiver, the price of a handheld observation glass is about US $ 5,500; also a viewfinder for the smallest gun is also 6,500 USD. If you buy design and assembly line technology for only one type of glass, the price is not less than a few million USD.

Over three years, the research team created three product groups from this technology process. The most important is to research and develop and design the process of complex optical lens system, design digital control electronic circuits, image processing and control software. Along with that is to build a technological process of manufacturing lenses with a diameter of 60-180 mm with a radius of error of 0.0005 mm; surface error 0.000125 mm.

From here, a series of night vision goggles have been built, from a compact type of hand-held observation glass of just a few hundred grams to a range of up to 5-8 km; glass observing the eyes, glasses attached to the driver's forehead; viewfinder, glass with camera on night. Especially the night viewfinder built by the subject can clearly see the target at a distance of up to 1 km in a completely dark condition by using an invisible laser projection system.

According to Mr. Vu Ba Huan, a member of the research team, the biggest success of the research team is to rely heavily on domestic internal resources to design and manufacture such a high-tech product . This work includes a series of dozens of stages to study, from optoelectronic, laser, optical lenses, vacuum film coating, image processing to design technological processes: optical machining , precision engineering, electronic-automatic control, product assembly . until the smallest stages of processing, which stage is new, from the beginning.

'In the future, the research team will focus on improving technology and commercializing products on the basis of state investment as well as joint ventures with some outside companies. On the basis of inheriting the achieved results, we will focus on the research and application of advanced and visual optoelectronic components for robots (monitoring, automatic measurement .), microscope and some special optical devices for defense, security, health and some other areas, " said the chairman of the project.

The success of the research team may open up many new industries as well as promote many supporting industries related to the development of super clean materials, chemicals, precision mechanics, optoelectronic microelectronics, programming . These types of products have been highly appreciated by the scientific community, ensuring the same quality as imported products and equipment, but have lower prices and are likely to apply in many important areas. The successful research, mastering the technology of manufacturing night vision goggles is considered a technology platform that opens up the direction of high-tech field development which is quite new in Vietnam.
