Title: Optical shutter
Inventor: SATO MASUJI
IPC: G02F1/13
Filed: 1988-01-22
Abstract: PURPOSE:To execute the high speed of a response speed by providing two polarizers and a turning means to turn a liquid crystal cell with an axis orthogonal to an incident light as a center, turning a liquid crystal cell, changing the incident angle of the light and changing the intensity of an emitted light. CONSTITUTION:Linear polarizing plates 1 and 3, in which a polarizing direction is 45 deg. for a turning axis 4, are arranged both before and behind an equally arranged liquid crystal cell 2 and the liquid crystal cell 2 is turned around the turning axis 4 in a constant angle range by a turning means due to a motor. The optical shutter is not the one using the change of a molecular arrangement due to the electric field impression but the one to use the permeability change of the liquid crystal cell 2 due to the change of the incident angle of a beam. At such a time since the angle change of the liquid crystal cell is controlled by the motor, the response speed of the shutter is determined by the fluctuation speed of the motor. Thus, the controllability is improved and the high speed can be executed.
