ABSTRACT:
An optical apparatus is disclosed. The optical apparatus includes: a first optical element having a first polarizing layer containing a material having a refractive index that changes in accordance with the magnitude of applied voltage and first and second transparent electrodes sandwiching both sides of the first polarizing layer in the direction of thickness and polarizing light passing through the first polarizing layer in the direction of thickness; and a second optical element having a second polarizing layer containing a material having a refractive index that changes in accordance with the magnitude of applied voltage and third and fourth transparent electrodes sandwiching both sides of the second polarizing layer in the direction of thickness and polarizing light passing through the second polarizing layer in the direction of thickness.
