[0050] EXAMPLES: Optical micro-hand used for cell capture and posture adjustment.

[0051] like Figure 19 As shown, the fiber grating demodulation module 18 is added to the optical microfabrication system for fiber ambient temperature monitoring. The entire system and connection relationship are:

[0052] Ten Channel Power Light Source 1 Select an LD pump laser having a wavelength of 980 nm, and output power is 0 to 100 mW per channel. The wavelength is small in the water environment, and the cell 17 can be effectively avoided by laser local heating. The channels 1-1 to 1-8 of the ten-channel power source 1 are connected to the nine-core fiber fan into the fan-out device 5, and the eight peripheral cores of the nine-core optical fiber 2 correspondence. The light wave output by the ninth passage 1-9 of the ten-channel power source 1 is divided into two ways of 3dB fiber coupler 6, wherein all the way to connect the first fiber attenuator 7-1 and the fiber phase modulator 8 after ac...

Abstract

The invention provides a flexible optical micro-hand system and a particle control method. The flexible optical micro-hand system is characterized in that the optical micro-hand system comprises a ten-channel power light source, an optical fiber coupler, a first optical fiber attenuator, a second optical fiber attenuator, an optical fiber phase modulator, a three-core optical fiber fan-in and fan-out device, a three-core optical fiber, a nine-core optical fiber fan-in and fan-out device, a nine-core optical fiber, a microscope and a computer. The nine-core optical fiber is provided with a 3*3 square distributed fiber core, the fiber end of the nine-core optical fiber is provided with a cone circular truncated cone structure, control light beams in eight peripheral fiber cores can be reflected and focused, and the middle core of the nine-core optical fiber is a few-mode fiber core. By controlling the intensity and phase of the control light transmitted in the fiber cores, the attitude adjustment functions of capturing, rotating and the like of the particles can be realized, and the directional transportation function of the particles can also be realized. The system and the method can be widely applied to the field of complex particle light manipulation.

Description

technical field [0001] The invention relates to a flexible optical microhand system and a particle manipulation method, and belongs to the technical field of optical tweezers micromanipulation. Background technique [0002] Optical tweezers technology refers to the technology of trapping and manipulating particles by using a single beam or multi-beam combined light field to form a trapping potential well for particles. Since Askin proposed a three-dimensional optical potential well based on a single-beam laser in the article "Observation of asingle-beam gradient force optical trap for dielectric particles" in 1986, which is used to realize the three-dimensional space control of particles, the "optical tweezers" Technology has gradually become familiar to people and has been greatly developed. The invention of optical tweezers has enabled people to obtain tools for manipulating tiny particles, which has promoted the rapid development of many interdisciplinary subjects, espec...
