The invention discloses a piezoelectric excitation mode switching type micro-control measurement system and method. The measurement system comprises a micro-control device, a microscopic detection device and a calculation device, wherein the micro-control device comprises a container, a base plate, four transducers, four fixing bolts and four fixing cylinders; the transducer comprises a connecting circular truncated cone, a connecting column, a piezoelectric ceramic module, a pre-tightening column and a pre-tightening bolt; and the container is fixed to the top of the four transducers, and the bottom parts of the four transducers are fixed to the base plate through the four fixing cylinders respectively. During working, the microscopic detection device observes an image of microspheres in the micro-control device container on the objective table and transmits the image to the calculation device; and the calculation device analyzes the image and obtains the motion trail and morphology parameters of the microspheres through machine learning. The measurement system is simple in equipment and low in price, lossless and non-contact control over the microspheres is achieved through the piezoelectric excitation micro-control device, and the motion trail and morphology parameters of the microspheres can be rapidly obtained.

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
