A introduction of Holographic optical tweezers system

Based on the liquid crystal pure phase spatial light modulator as a holographic optical element, the wavefront phase shaping of the light field is performed to generate an optical trap array. The computer loads and converts the holographic image in real time to control the position of the light trap. By generating a holographic pattern of a preset shape, multiple particles can be captured and manipulated in three-dimensional space at the same time. The particles in any light trap in the array can be captured and manipulated simultaneously. Perform independent dynamic control. In addition, by generating a new type of light trap, operations such as rotation, transportation and sorting of particles can also be completed.

Product Detail

Optical Tweezers work by utilizing the mechanical effects of the interaction between light and matter . A beam with a certain light intensity distribution can generate a force on the order of cows to capture tiny particles, so it can clamp and transport particles like ” tweezers ” without causing mechanical damage. Based on the penetration characteristics of light, it can also operate component particles deep inside without damaging the surface of the particles.

Optical tweezers have the characteristics of non-mechanical contact, low damage, rich manipulable objects, and high-precision measurement of small displacements and forces. They have been widely used in basic research in interdisciplinary disciplines such as life sciences, physical chemistry, and aerosol science. And it has shown great potential in applications such as micro-nano processing and sensing measurement.

The Holographic Optical Tweezers (HOT) system SLM-HOT is based on a liquid crystal pure phase spatial light modulator (SLM) as a holographic optical element, which performs wavefront phase shaping of the light field to generate an optical trap array. The computer loads and converts the holographic image in real time, thereby controlling the position of the light trap. The particles in any light trap in the array can be independently and dynamically controlled. In addition, by generating a new type of light trap, operations such as rotation, transportation and sorting of particles can also be completed.

Holographic optical tweezers are different from traditional optical tweezers technology. They can add phase modulation in single or multiple optical traps to generate special modes of focal field light field distribution such as Bessel beams and vortex beams.
