Optical radiator can improve the working accuracy of LiDAR by 10 times

The optical radiator is an optical radiation instrument jointly developed by scientists from the Physics, Nanotechnology, and Electronics Department of St. Petersburg State Technical University and the Moscow State Institute of Electronic Technology. It can improve the accuracy of laser radar operation10Twice. This speed increase can be used to scan shorter optical pulses in modern radiators.
Optical radar is a device composed of three main components used to determine distance: a radiator that sends optical signals (usually a laser beam), a receiver that captures reflected signals from various objects around the radar, and a surrounding terrain image data processing system constructed based on feature differences and time intervals between signals and delayed signals.
　　
Therefore, the shorter the duration and higher the power of the optical radar scanning pulse, the higher the working range and accuracy of the radar. Only by improving the working accuracy of the laser radiator can the radar performance be improved. We have reduced the pulse duration while maintaining the pulse power, greatly improving the range and operational accuracy of the radar. This requires the development of a new component substrate and the use of a completely new electronic device structure, "said Alexei Philimonov, head of the Department of Physical Electronics at St. Petersburg State Technical University.
　　
The new optical radiator is a chip with a matching head size that can be used for standard applicationsLEDShell or laser. It has a shorter pulse duration than similar devices currently in use5Twice. The chip itself can utilize layered metals-The original methods of insulator structure technology and electronic component configuration are produced in Russia.
