1. An optical element comprising:

  • a pair of transparent substrates disposed so as to be opposed to each other;

    a liquid crystal disposed between the pair of transparent substrates and having optical isotropy; and

    transparent electrodes formed between the liquid crystal and the transparent substrates, for applying a voltage to the liquid crystal;

    wherein the refractive index of the liquid crystal changes depending on the voltage applied via the electrodes.
