Description

technical field [0001] The invention relates to the fields of micro-manipulation and rapid screening of micro-particles, in particular to a piezoelectrically excited mode-switching micro-manipulation measurement system and a method thereof. Background technique [0002] Laser Confinement Fusion ICF uses high-power, high-energy-density lasers as the driving source, and adopts spherical implosion pressurization technology to make the nuclear fuel in the spherical target pellet reach the ignition conditions, thereby forming a self-sustaining thermonuclear reaction. ICF is expected to provide clean and pollution-free energy for mankind. ICF experiments have strict requirements on the quality of hollow microspheres (target pellets) as nuclear fuel containers in terms of geometric parameters and surface defects. The quality of target pellets directly affects the success or failure of ICF targeting experiments. At present, the detection equipment used for measuring the geometric p...

Problems solved by technology

However, these devices have the disadvantage of low detection efficiency, and the microspheres are all detected manually, and the subjective factors of personnel have a great influence on the screening of microspheres

At present, the amount of preparation of a single batch of target pellets is huge, and the detection efficiency of existing equipment is low, so it is impossible to use all high-precision screening methods. There is an urgent need for a device for rapid measurement and screening of microspheres to improve the screening of microspheres. efficiency
