Development of a variable beam deflector with simple structure using liquid crystal devices

摘要

At present, we have studied and developed a liquid crystal device applied to the optical device. A liquid crystal device is useful for the transformation of polarization and phase (wave front) of the light. This device is excellent in the miniaturization of the device and static because it is not necessary to use a mechanical movement and can control the light electrically. Moreover, their devices are trustworthy as optical devices and there make practicable as the wave front control devices (aberration compensators) applied for DVD optical pick up systems. This time, we report a beam deflector using liquid crystal devices we have developed.
