摘要

We adopt double-plate sheering interferometers to perform an optical tweezers array system. In the optical tweezers array system, the reflecting mirror is replaced by an optical scanner to be a beam translator. The optical scanner is driven by an input signal to control the interference strips movement. However, if the interference strips move periodically, the trapped particles would move along with the strips with the same regulation. So, the particles could not be separated from the other particles. We use an external modulating device to be a shutter to control the laser beam. Then the trapped particles would continue moving because of inertia during the laser beam is blocked, and be trapped again after the shutter opens. If the moving speed of liquid is limited properly, the particles can be separated continuingly and collected. At the end of this article, we illustrate the result of conducting the novel method and characteristics of the system.
