| Outline of Final Research Achievements |
We have developed the afocal Liquid Crystal (LC) Wide Angle Fovea optical lens system, by which the attention point can change very rapidly without any mechanical part. Since the response time of the LC lens cell increases in proportion to square of a thickness of its LC layer, this afocal optical system can achieve the rapid attention point change even if the thickness is thin. On the other hand, its performance as a lens system is not enough but very dark because of removing optical rays except those parallel and nearly-parallel to the optical axis. This study indicates we can design in advance the performance and specification of this LC zoom lens unit part using its mathematical model, in which the lens power of the applied LC lens cell, the achieved magnification change, and the distance between the two cells are paid attention to. Also we have compared the results with the conventional zoom lens applying the Galirean and Keplerian telescopic structures, respectively.
