Optical tweezers are a relatively new technique for non-invasive manipulation of micro particles. It has applications in different scientific and technological areas, such as: cell and molecule sorting, nano device assembly, and analysis of bio motors. Standard methods to create optical tweezers rely on using either the manipulation of a single beam or a spatial light modulator. Here a new optical tweezer design is presented that employs concepts from the realm of adaptive optics. The prototype system employs a deformable mirror to control the 3D position of the traps. A specific closed-loop control algorithm, adapted from adaptive optics technology allows a real-time precise monitoring of the deformable mirror shape and provides exquisite accuracy in trap placement. The first results obtained with the prototype design are presented.
