| Outline of Final Research Achievements |
In this study, high-speed optical lenses using acoustic radiation force and its application to micro-optical devices were developed. The lens can change its focal point by deforming the lens profile in a similar manner as the crystalline lens of the human eye. The high-speed response is expected by using acoustic radiation force.
The applications to micro-optical devices such as lens arrays and optical scanners were also developed. A novel technique to control the liquid molecular orientation was proposed and investigated.
