Problems solved by technology

However, due to the various forms of this operation, the correspondence between phase adjustment and each operation form is also very complicated, the particles themselves and the solution also have certain uncertainties, and often there are situations where the operation is not in place or the operation is wrong, making The operation is not accurate, the most important thing is that it cannot be corrected in time
Caused many problems in the practical application of optical tweezers

Description

technical field [0001] The invention relates to an optical micro-manipulation system, in particular to an adjustable wave front phase optical micro-manipulation system and a control method thereof. It is mainly used in the fields of laser micromachining, optical micromanipulation, optical information storage, and interaction between light and matter. technical background [0002] Optical micromanipulation system refers to the system that utilizes optomechanical effects such as optical gradient force and scattering force to manipulate and trap tiny particles. The particles that can be captured by the optical micromanipulation system can range from a few nanometers to tens of microns, which can be inanimate particles, living cells or viruses, etc. The research on light beam levitation and trapping of tiny particles can be traced back to the 1970s. The system to realize light levitation and trapping of tiny particles was successfully developed by Ashkin's research group, and w...
