Scientists from the Department of Physics, Nanotechnology and Electronics of the St. Petersburg State Technical University and the Moscow State Institute of Electronics Technology have jointly developed optical radiators that can improve the accuracy of laser radar operations by a factor of 10. This speed increase can be used to scan for shorter optical pulses in modern radiators.
The shorter the duration of the optical radar scan pulse, the higher the power, the higher the radar's working range and accuracy, and the improved radar performance can only be improved by the improved accuracy of the laser radiator. “We have reduced the pulse duration while maintaining the pulse power, which greatly improved the range and accuracy of the radar. This requires the development of a new component matrix and the use of a completely new structure of electronic equipmentâ€, St. Petersburg State Technical University Physics Electronics The head of the department, 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 produced in Russia entirely using the original method of layered metal-insulator structure technology and electronic component configuration.
Scientists presented their research results at the 16th International Conference on Internet of Things, Smart Space and Next Generation Networks and Systems (NEW2AN 2016), which was held in September 2016. The IEEE's on Electron Devices is the basic principle of the device. Reported. Now, scientists are looking for partners in the domestic business and scientific community to make laboratory prototypes into industrial designs. According to scientists, this research and development can be widely used in automotive, aircraft construction, shipbuilding, optical detection and automatic identification systems for various surrounding environments (computer vision systems). Therefore, optical radar, also known as laser radar, is one of the main components of unmanned vehicle electronics, and any improvement in performance and cost reduction may bring significant progress in the field of autonomous vehicles.
