    Patent number: 8619354
    Abstract: A high speed optical shutter, a method of operating the high speed optical shutter, and an optical apparatus including the high speed optical shutter. The optical shutter includes a transparent electro-optical medium in an active solid state having a total internal reflection surface on which an angle of total internal reflection is changed by an external action. The transparent electro-optical medium may be a prism or a prism array whose angle of total internal reflection is changed by the external action. An incident light path changing unit may be further arranged in front of the transparent electro-optical medium. Also, a light path changing unit may be further arranged so as to allow light passing through the electro-optical medium to be perpendicularly incident on an incidence target object.
