The effect of grain size on electric properties has been investigated. Various (111) oriented PLZT films were prepared using the RF magnetron sputtering method on Pt/Ti/SiO2/Si substrates. Grain size and surface roughness were observed by AFM. The re

An ultrahigh accuracy 3-D profilometer using a laser heterodyne interferometer has been developed. The profiles of aspheric lenses and their molds have been measured. It can measure not only the rectangular coordinates but also the polar coordinates

We have developed an Ultrahigh-Accurate 3-D Profilometer (UA3P), which, using a new, in-house-developed atomic force probe, has an accuracy of 10 nm. It is capable of measuring corners as small as 2 micro meter in radius and can cover an area up to 4

To apply the optical disk to data memory systems, faster random access is an essential requirement. We have developed a fast access actuator, the structure of which is fundamentally different from that of the conventional actuator. The optical head c
