We implemented an integrated time sharing multiple optical trapping system through the synchronisation of
high speed voice coil scanning lens and laser pulsing. The integration is achieved by using commonly available
optical pickup unit (OPU) that exists inside optical drives. Scanning frequencies of up to 2 kHz were showed to
achieve arbitrary distribution of optical traps within the one-dimensional scan range of the voice coil motor. The
functions of the system were demonstrated by the imaging and trapping of 1 μm particles and giant unilamellar
vesicles (GUVs). The new device circumvents existing bulky laser scanning systems (4f lens systems) with an
integrated laser and lens steering platform that can be integrated on a variety of microscopy platforms (confocal,

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
