A detailed research of optical trapping of nematic and chiral nematic liquid crystalline droplets is presented, in which the central study is the droplet behaviour in the optical traps and relevant mechanisms. The study consists of two main works: a generalized investigation of the rotational dynamics of optically trapped droplets, and a novel rotational behaviour of specific chiral nematic droplets in linearly polarized laser traps. Studies Into the physical properties of nematic and chiral nematic liquid crystals, principles of optical tweezers, and the director configuration of liquid crystal droplets act as the important basis for the investigation into relevant mechanisms of the droplet behaviour in the optical traps.
