The measurement system includes a micro-control device, a microscopic detection device and a computing device; the micro-manipulation device includes a container, a pretension module, The piezoelectric ceramic module and the fixed cylinder; one end of the pretension module is connected to the fixed cylinder, and the other end is connected to the container, and the piezoelectric ceramic module is clamped in it; the microscopic detection device adopts a commercial industrial microscope, and the lower end of the fixed cylinder is placed in a microscope Place the container horizontally on the stage of the detection device. When working, the microscopic detection device observes the image of the microsphere in the container and transmits it to the computing device; the computing device analyzes the received image, and obtains the trajectory of the microsphere and its shape parameters through machine learning. The invention has simple equipment and low price, adopts a micro-control device excited by piezoelectricity to realize non-destructive and non-contact control of the microsphere, and can quickly obtain the motion trajectory and shape parameters of the microsphere.

Description

Technical field [0001] The present invention relates to a micro manipulation and rapid screening microparticles, and more particularly, to a microsphere open standing wave field of a micro control system and a measuring method. Background technique [0002] Confinement Fusion ICF laser is a high power, high energy density of the laser as a driving source, the use of spherical fuel explosion technology to boost inner spherical capsule reaches the ignition condition, thereby forming a self-sustaining thermonuclear reaction. ICF is expected to provide clean as humans, non-polluting energy. ICF experiment for the quality of a fuel container, hollow microspheres (pellet) has strict requirements in terms of geometry, surface defects, the quality of the capsule directly affect the success ICF targeting experiments. Currently, the detection device for measuring the geometric parameters of the microspheres employed, the X-ray apparatus, a white light interferometer, an atomic force micros...

Problems solved by technology

However, the detection efficiency of these devices is very low, and all of them use manual detection, and the subjective factors of microsphere screening are greatly affected

Moreover, due to the huge amount of preparation of target pellets and the low detection efficiency of existing equipment, it is impossible to use all high-precision screening methods. Therefore, a device for rapid measurement and screening of microspheres is urgently needed to improve the screening efficiency of microspheres.
