A Stereoscopic Display
with a Vibrating Microlens Array


 

We demonstrate a prototype of a highresolution 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 measure 12.5 µm and 320 µm, and therefore the focal length can be calculated as 1980 µm. 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 µm and 120 ms, respectively.
