In the near future, the chip has become a hot term. A chip developed by Suzhou Changguang Huaxin Company for mobile phone face recognition system is really eye-opening.
This surface-emitting laser chip is mainly used in mobile phone 3D face recognition system. It is currently the only chip in China that realizes this function. Changguang Huaxin is also one of the few companies in the world that only develops and mass-produces high-power semiconductor laser chips. . Through long-term practice accumulation, the development of this application and face recognition chip has only been used for more than a year.
Semiconductor lasers are widely used in optical communication, optical sensing, and defense construction. However, for a long time, core chip technology has been monopolized by foreign countries and has strict export control. Since 2012, Suzhou Changguang Huaxin team has started research and solved many technical problems in epitaxial growth technology, cavity surface passivation technology and device fabrication technology level, and formed a high-power semiconductor with independent intellectual property rights. The full range of laser products, the cumulative sales of more than 2 million chips.
Yan Dayong, chairman of Suzhou Changguang Huaxin Optoelectronic Technology Co., Ltd. said that the chip should be said to be a relatively large investment and long-term industry. Our original advantage lies in the high-power semiconductor chips. Therefore, the semiconductor laser chips for driverless cars in the future should be difficult for us. The most important thing is to allow failure. This platform can attract more talents.
In the future IoT world, to accurately perceive the information of objects, we must rely on laser vision technology. In the next step, Changguang Huaxin Optoelectronics will be based on the development and research of high-power chips, and accelerate the application development of civilian products, such as the core chip production and application in driverless driving, and truly change the "no core" in the laser field in China. history. It can be said that in the high-tech field, Suzhou enterprises are not absent.
Germany type extension socket are used in most European countries such as Germany, Austria, the Netherlands, Sweden, Norway, Finland, and Russia.
High quality Copper with GS and CE standard sleeve design, strong elasticity, precision mesh, effectively prevent arc generation, normal plug and pull 10000 times do not loose.
The body of power strips are small and tiny, does not take up space, travel essential.
