At the same time, optical tweezers technique has developed greatly and many extended techniques are proposed, enlarging optical tweezers family. Holographic optical tweezers, formed by hologram device or spatial light modulator (SLM), has new features in practical and large -scale production of optical tweezers for its advantages in multi - particle micro-manipulation. Now holographic optical tweezers is one of the most important members in optical tweezers′ family. The basic principle of holographic optical tweezers and the most recent research progress and potential application of this vigorous technology are introduced. Key words opt
