Advantages of Holographic Optical Tweezers

Novel Optical Instrumentation for Biomedical Applications, 2003
In the last decade optical tweezers became an important tool in microbiology. However the setup becomes very complex if more than one trap needs to be moved. Holographic tweezers offer a very simple and cost efficient way of manipulating several traps independently in all three dimensions with an accuracy of less than 100 nm.

Dynamic holographic optical tweezers

Optics Communications, 2002
Optical trapping is an increasingly important technique for controlling and probing matter at length scales ranging from nanometers to millimeters. This paper describes methods for creating large numbers of high-quality optical traps in arbitrary three-dimensional configurations and for dynamically reconfiguring them under computer control.

Surface imaging using holographic optical tweezers

Nanotechnology, 2011
We present an imaging technique using an optically trapped cigar-shaped probe controlled using holographic optical tweezers. The probe is raster scanned over a surface, allowing an image to be taken in a manner analogous to scanning probe microscopy (SPM), with automatic closed loop feedback control provided by analysis of the probe position recorded ...
