Positioning Accuracy in Holographic Optical Traps
Micromachines, 2021 Spatial light modulators (SLMs) have been widely used to achieve dynamic control of optical traps. Often, holographic optical tweezers have been presumed to provide nanometer or sub-nanometer positioning accuracy.

Artifact-free holographic light shaping through moving acousto-optic holograms
Scientific Reports, 2021 Holographic light modulation is the most efficient method to shape laser light into well-defined patterns and is therefore the means of choice for many intensity demanding applications.

Review of Scientific Instruments, 2004 Since their invention just over 20 years ago, optical traps have emerged as a powerful tool with broad-reaching applications in biology and physics. Capabilities have evolved from simple manipulation to the application of calibrated forces on—and the measurement of nanometer-level displacements of—optically trapped objects.

Optical trapping core formation and general trapping mechanism in single-beam optical tweezers
New Journal of Physics, 2022 The working mechanism of single-beam optical tweezers is revisited using a recently established method. The optical force is split into conservative and nonconservative components, and these components are explicitly calculated for particles in the ...

Optical trapping at low numerical aperture [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 A theory of optical trapping at low Numerical Aperture (NA) is presented. The theory offers an analytical description of the competition between the stabilizing gradient and destabilizing scattering force.

Independent trapping, manipulation and characterization by an all-optical biophotonics workstation [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 Optical trapping has enabled a multitude of applications focusing, in particular, on non-invasive studies of cellular material. The full potential of optical trapping has, however, not yet been exploited due to restricted access to the trapped samples ...
