Estimating the term…
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.
An optical shutter comprising:
A method of operating an optical shutter including an electro-optical medium, the electro-optical medium being transparent and in an active solid state, and wherein the electro-optical medium includes a total internal reflection surface at which an angle of incidence above which total internal reflection occurs is changeable in response to an input, the method comprising changing the angle of incidence above which total internal reflection occurs by applying a voltage to the electro-optical medium.
An optical apparatus comprising:
