St Petersburg State Technical University, Department of Physics, Nanotechnology and Electronics, Moscow State Institute of Electronic Science and Technology scientists jointly developed optical radiator, which can improve the accuracy of laser 5000mw radar 10 times. This increase in speed can be used to scan shorter optical pulses in modern radiators, the St. Petersburg State Technical University Press Center reported. An optical radar is a device consisting of three main components for determining the distance: a radiator that transmits an optical signal (usually a laser beam), a receiver that captures the reflected signals of various objects around the radar, and a receiver which distinguishes it according to a characteristic difference, The time interval between the delayed signals is constructed around the terrain image data processing system.
Therefore, the shorter the pulse duration and the higher the power, the higher the range and accuracy of the radar. "We have reduced the pulse duration while maintaining the pulse power, which greatly improves the range and accuracy of the radar, which requires the development of a new element matrix and the use of a completely new electronic device" "Said Alexei Filimonov, director of the Department of Electronics.
The new optical radiator is a chip with a matching head size that can be used with standard LED housings or lasers. Which is 5 times smaller than the pulse duration of similar devices currently in use. The chip itself can be produced entirely within Russia using the original method of layered metal-insulator structure technology and electronic component placement. Scientists presented their findings at the 16th International Conference on the Internet of Things, Smart Space and Next Generation Networks and Systems (NEW2AN 2016), held in September 2016, and the IEEE Transactions on Electrons (EI) Devices have reported the basic principles of the device.
Now, scientists are looking for partners in the domestic business and scientific community to make laboratory prototypes into industrial designs. Scientists, the research and development can be widely used in automotive, aircraft construction, shipbuilding, optical detection and a variety of peripheral automatic identification system (computer vision system). Therefore, the optical radar can also be called 20000mw laser radar, it is unmanned vehicle electronic equipment, one of the main components, the performance of any improvement and cost reduction may bring significant progress in the field of autonomous vehicles.
