Experimental demonstration of holographic three-dimensional light shaping using a Gerchberg–Saxton algorithm
We use a three-dimensional Gerchberg–Saxton algorithm (Shabtay (2003) Opt. Commun. 226 33) to calculate the Fourier-space representation of physically realizable light beams with arbitrarily shaped three-dimensional intensity distributions. From this representation we extract a phase-hologram pattern that allows us to create such light beams experimentally. We show several examples of experimen...
متن کاملHolographic optical tweezers combined with back-focal-plane displacement detection.
A major problem with holographic optical tweezers (HOTs) is their incompatibility with laser-based position detection methods, such as back-focal-plane interferometry (BFPI). The alternatives generally used with HOTs, like high-speed video tracking, do not offer the same spatial and temporal bandwidths. This has limited the use of this technique in precise quantitative experiments. In this pape...
متن کاملHolographic 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 کاملImproved direct binary search-based algorithm for generating holograms for the application of holographic optical tweezers
This paper presents an improved direct binary search (DBS)-based algorithm for generating holograms to holographic optical tweezers. The simulations show that the improved algorithm greatly enhances computation speed while maintaining high hologram efficiency and high-intensity homogeneous target spots. The improved algorithm was applied to generate holographic optical tweezers in several exper...
