This video shows how many optical traps can be generated from a single laser source by rapidly scanning the laser across many positions, a process called multiplexing. This multiplexing is in a way similar to juggling: not all objects are manipulated at the same time, but intermittently grabbing hold of each one of them still allows to control them all.
JPK’s NanoTracker optical tweezers platform has such multiplexing functionality integrated into the software, allowing for versatile manipulation of many objects.
