A new type of the fine pointing mechanism (FPM) was examined as part of the optical ISL studies conducted by NASDA. Compact piezo-electric mirror deflecting mechanism (MDM), having a very high resolution (less than 3 microrad) was fabricated, and the performance of the MDM was evaluated aiming for application in the ISL optical FPM. The fundamental performance of the fine pointing assembly (FPA) in optical ISL with the multi-layered piezo-electric MDM was confirmed sufficient for optical ISL having pointing error by disturbance (plus/minus 0.75 microrad) and pointing angle (plus/minus 720 microrad). It was confirmed that the examined FPM is suitable for the fine pointing of optical ISL, by combining appropriately designed optics and coarse pointing assembly (CPA), through a preliminary system design.
