Fig. 19.2 — Aerosol optical tweezers
(a) Schematic of an experimental set-up to optically trap aerosols, including a nebuliser to produce aerosol droplets, an SLM to generate multiple optical traps and a CCD camera to track the position of the droplets. (b) A 4 × 4 array of optical traps, whose trapping sites are populated by aerosol droplets over time as shown in (c) and (d).
