Holographic optical tweezers
The craze for miniaturization has swept o’er most every nation, but should a hand e’er so slightly tremble no micro-machine can it assemble: and so all those really small bits leave the technicians in fits and the hope for a lab on a chip might seem frightfully flip. Yet, while optical forces are weak they provide the control that we seek. When light’s holographically defined, HOT opportunities...
متن کاملDynamic Holographic Optical Tweezers
Optical trapping is an increasingly important technique for controlling and probing the structure of matter at length scales ranging from nanometers to millimeters. This Article describes methods for creating large numbers of high-quality optical traps in arbitrary three-dimensional configurations and dynamically reconfiguring them under computer control. The resulting traps’ unique capacity fo...
متن کاملCombined holographic-mechanical optical tweezers: Construction, optimisation and calibration
We have combined a spatial light modulator (SLM) and galvanometer-mounted mirrors into an optical tweezers set-up. This provides great flexibility by allowing us to create an array of traps which can be moved in a smooth and fast way. To optimise the performance we investigated the effect of incidence angle on the SLM with respect to phase and intensity response. Although it is possible to use ...
متن کاملCombined holographic-mechanical optical tweezers: construction, optimization, and calibration.
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. To optimize performance, the effect of the incidence angle on the SLM with respect to phase and intensity response was investigated. Although it i...
متن کاملProcessing carbon nanotubes with holographic optical tweezers.
We report the first demonstration that carbon nanotubes can be trapped and manipulated by optical tweezers. This observation is surprising because individual nanotubes are substantially smaller than the wavelength of light, and thus should not be amenable to optical trapping. Even so, nanotube bundles, and perhaps even individual nanotubes, can be transported at high speeds, deposited onto subs...
