“…First, static diffractive optical elements generated by computer and manufactured by photolithography, enabled the simultaneous creation of several optical traps [1,2]. Conversion of the static trap arrays into dynamic light patterns by displaying the diffractive optical elements on spatial light modulators was the logical next step [3][4][5][6]. These special displays can be updated at video rates, so that with every new diffractive element a completely different optical potential is formed at the sample plane.…”

Abstract. We provide a detailed account of the construction of a system of holographic optical tweezers. While a lot of information is available on the design, alignment and calibration of other optical trapping configurations, those based on holography are relatively poorly described. Inclusion of a spatial light modulator in the setup gives rise to particular design trade-offs and constraints, and the system benefits from specific optimization strategies, which we discuss.

“…Spatial light modulators have been used as non-mechanical alternatives to mirror scanning for dynamic light shaping to directly control the motion of microscopic particles [1,2]. Combined with specially designed microscopic tools having built-in waveguides [3], dynamic light shaping can be used to deliver highly focused light into specific cellular targets.…”

This work discusses the use of matched filtering Generalized Phase Contrast (mGPC) as an efficient and cost-effective beam shaper for applications such as in biophotonics, optical micromanipulation, microscopy and two-photon polymerization. The theoretical foundation of mGPC is described as a combination of Generalized Phase Contrast and phase-only correlation. Such an analysis makes it convenient to optimize an mGPC system for different setup conditions. Results showing binary-only phase generation of dynamic spot arrays and line patterns are presented.

“…Optical tweezers systems are available commercially and they have found a number of applications, 3 including measuring the compliance of bacteria, 4 measuring the forces exerted by motor proteins 5,6 and trapping metal nanoparticles. 7,8 Holographic optical tweezers [9][10][11][12][13] employ spatial light modulators (SLMs), used as dynamic computer-controlled diffractive optical elements, to manipulate many objects independently. They have found many applications including the construction of 3D structures using micron-sized dielectric spheres 14 or living cells 15 and imaging soft cellular surfaces using optically trapped probes.…”

Holographic optical tweezers have found many applications including the construction of complex micron-scale 3D structures and the control of tools and probes for position, force, and viscosity measurement. We have developed a compact, stable, holographic optical tweezers instrument which can be easily transported and is compatible with a wide range of microscopy techniques, making it a valuable tool for collaborative research. The instrument measures approximately 30×30×35 cm and is designed around a custom inverted microscope, incorporating a fibre laser operating at 1070 nm. We designed the control software to be easily accessible for the non-specialist, and have further improved its ease of use with a multi-touch iPad interface. A high-speed camera allows multiple trapped objects to be tracked simultaneously. We demonstrate that the compact instrument is stable to 0.5 nm for a 10 s measurement time by plotting the Allan variance of the measured position of a trapped 2 μm silica bead. We also present a range of objects that have been successfully manipulated.
