Abstract :
In this paper, we demonstrate a prototype of a high-resolution stereoscopic display by vibrating a micro cylindrical lens array. This lens array is fabricated by melting photoresists and form transfer. The height and width of the cylindrical lens measured 12.5 /spl mu/m and 320 /spl mu/m, therefore the focal length is calculated as 1980 /spl mu/m. The lens array vibrates synchronously with the changeover of images which are displayed under the lens array. The brightness is measured at several view angles, and 9 degrees-parallax is observed on condition that the amplitude and cycle of the vibration are 100 /spl mu/m and 120 ms, respectively.
