A vector holographic optical trap. [PDF]
Sci Rep, 2018 AbstractThe invention of optical tweezers almost forty years ago has triggered applications spanning multiple disciplines and has also found its way into commercial products. A major breakthrough came with the invention of holographic optical tweezers (HOTs), allowing simultaneous manipulation of many particles, traditionally done with arrays of scalar

Quantum efficiency improvement of optical radiation trap-detectors
Semiconductor Physics, Quantum Electronics & Optoelectronics, 2019 The ways to increase the quantum efficiency of trap detectors of optical radiation have been discussed. Presented here has been a brief review of trap detectors, in which high quantum efficiency is ensured by their design.

Microrheology With an Anisotropic Optical Trap [PDF]
Frontiers in Physics, 2021 Microrheology with optical tweezers (MOT) measurements are usually performed using optical traps that are close to isotropic across the plane being imaged, but little is known about what happens when this is not the case. In this work, we investigate the effect of anisotropic optical traps on microrheology measurements.

Optical micromanipulation of aerosols [PDF]
, 2009 This thesis describes my work on the development of optical trapping techniques for manipulating airborne particles. Although many of the basic principles are similar to those used in more conventional colloidal experiments, there are many differences

Simulation of superresolution holography for optical tweezers [PDF]
, 2008 Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

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.
