Fine-particle bombardment (FPB) is typically used to modify metal surfaces by bombarding them with fine particles at high speed. FPB is not a coating technique but is used for forming microscale concavities and convexities on a surface. Previously, w

The development of high-resolution and large field of view remote-sensing cameras is inextricably linked to the application of free-form mirrors. The free-form mirror offers higher design of freedom and is more effective at correcting aberrations in

Due to the anisotropy of sapphire crystal material, the mechanical properties vary in multi-wire saw slicing based on different cutting positions. This variation leads to the deviation of the diamond wire in the vertical feed direction, resulting in

The key indicator of a grazing incidence focusing mirror’s imaging quality is its angular resolution, which is significantly influenced by its surface shape distribution error. In this paper, we propose a method for the prediction of grazing incide

It is difficult to predict the earthquake loading so the effect of pre-strain on fatigue strength was required to investigate. Especially, surface shape was changed when large plastic strain was applied. Strain concentration may be occurred by this s
