Scientists Collaborate to Increase Accuracy of Optical Radar
Earlier researches from SPbPU with colleagues from Moscow Institute of Electronic Technology and University of Oulu have developed an optical transmitter increasing the accuracy of optical radars nearly ten-fold. These are record indicators. Such results were achieved by applying shorter optical pulses, which duration is about one nanosecond, for the scanning procedure.
Reducing the pulse length while maintaining its power can significantly improve its accuracy: the typical indicators in similar devices are 30-40 V / 3-5 ns, while the device created in SPbPU demonstrates 40V / 1 ns, this is a unique achievement. This device might find a broad application range in shipbuilding, automobile, aircraft manufacturing, optical detection, and electronic equipment.
Now the aim of scientific consortium is to continue the collaboration for improving the characteristics of the optical emitter, in particular, to increase the radiating power, the pulse repetition rate and the transition to subnanosecond area.
