(Nanowerk Spotlight) Reporting their findings in Advanced Materials ("Time-division Position Sensitive Detector Image System for High-speed Multitarget Trajectory Tracking"), researchers in the School of Physics at Southeast University in Nanjing, China, demonstrate a multitarget real-time trajectory tracking system by using a time-division position sensitive detector (TD-PSD) system by employing a graphene-silicon Schottky heterojunction.
Benefiting from the high-speed optoelectronic response and submicrometer positional accuracy of the TD-PSD, the team realized multi-target real-time trajectory tracking with a maximum image output frame rate of up to 62 000 frames per second (which is superior to commercial optical high-speed motion capture systems of about
