Researchers 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. The system allows for 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 1000 frames per second). This breaks the bottleneck in precise ...
