Scientists have developed optical radiators to improve the accuracy of lidar 10 times

The faculty of Physics, Nanotechnology and Electronics of the State University of Technology in Saint Petersburg, in collaboration with the Moscow State Institute of Electronics and Technology, have jointly developed optical radiators that will increase the accuracy of laser radar up to 10 times. The faculty of Physics, Nanotechnology and Electronics of the State University of Technology in Saint Petersburg, in collaboration with the Moscow State Institute of Electronics and Technology, have jointly developed optical radiators that will increase the accuracy of laser radar up to 10 times. This speed increase can be used to scan shorter optical pulses in modern radiators, reports the Press Center, State Technical University, St. Petersburg. An optical radar is a device for determining the distance consisting of three main components: a radiator that emits an optical signal (usually a laser beam), a receiver that captures the reflected signals of various objects around the radar, Delays the time interval between signals to build the surrounding terrain picture data processing system. Therefore, the shorter the scan pulse duration, the greater the power, the higher the working range and accuracy of the radar. Therefore, the improvement of the radar performance can only be achieved by improving the working accuracy of the laser radiator. "We have reduced the pulse duration while maintaining the pulse power, which greatly increases the range and accuracy of the radar, which requires the development of a new element substrate and the use of a completely new electronic structure", St. Petersburg State Technical University Physics Department of Electronics director Alexei Filimonov pointed out. The new optical radiator is a chip with a matching head size that can be used with standard LED housings or lasers. It is 5 times smaller than the pulse duration of similar devices currently in use. The chip itself can be manufactured entirely in Russia using the original method of layered metal-insulator structure technology and electronic component placement. The scientists presented their findings at the 16th International Conference on IoT, Smart Space and Next Generation Networks and Systems (NEW2AN 2016) held in September 2016. The IEEE Transactions on Electron (IEEE Transactions on Electron) Devices reported the fundamentals of the device. Now scientists are looking for partners in the domestic business and scientific community to make laboratory prototypes into industrial designs. Scientists introduced the research and development can be widely used in automotive, aircraft construction, shipbuilding, optical detection and a variety of automatic recognition of the surrounding environment system (computer vision system). As a result, optical radar, also known as lidar, is one of the main components of autonomous vehicle electronics, and any improvements in its performance and cost reductions may lead to significant advances in the field of autonomous vehicles.
