To meet the high-precision requirement of microtarget assembly in inertial confinement fusion (ICF) experiments, this paper proposes a new technique for the size and position of measuring the size and position of the microsphere target in microtarget assembly. The technique employs two laser confocal probes of sub-micrometer precision to realize scanning measurement, and an algorithm based on matrix subdivision and two-step target extraction to implement calculation. The results show that a 2 m measurement precision has been achieved.
