Scanning holographic optical tweezers
Optics Letters, 2017 The aim of this Letter is to introduce a new optical tweezers approach, called scanning holographic optical tweezers (SHOT), which drastically increases the working area (WA) of the holographic-optical tweezers (HOT) approach, while maintaining tightly focused laser traps. A 12-fold increase in the WA is demonstrated.

Above and beyond: holographic tracking of axial displacements in holographic optical tweezers
Optics Express, 2019 How far a particle moves along the optical axis in a holographic optical trap is not simply dictated by the programmed motion of the trap, but rather depends on an interplay of the trap's changing shape and the particle's material properties. For the particular case of colloidal spheres in optical tweezers, holographic video microscopy reveals that ...

Holographic Optical Tweezers at the Tip of a Needle [PDF]
2018 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2018 Fibre-based optical tweezers typically rely on engineered fibre terminations yielding limited flexibility in number and positioning of trap sites. Here, we demonstrate holographic optical tweezers delivered by a lensless, high-NA multimode fibre with full positioning control of multiple tweezers independently and in all directions.

Hands-on with optical tweezers: a multitouch interface for holographic optical trapping
Optics Express, 2009 We report the implementation of a multitouch console for control of a holographic optical tweezers system. This innovative interface enables the independent but simultaneous interactive control of numerous optical traps by multiple users, overcoming the limitations of traditional interfaces and placing the full power of holographic optical tweezing ...

Combined holographic-mechanical optical tweezers: Construction, optimization, and calibration
Review of Scientific Instruments, 2009 A spatial light modulator (SLM) and a pair of galvanometer-mounted mirrors (GMM) were combined into an optical tweezers setup. This provides great flexibility as the SLM creates an array of traps, which can be moved smoothly and quickly with the GMM.
