1. A device for modulating light as a function of spatial position comprising:

  • a substrate;

    an array of temperature changing means deposited on the substrate; and

    a thin film comprising a vanadium oxide (VO) compound, the VO compound being deposited on the temperature changing means array;

    wherein, when an electrical current is applied to a temperature changing means, the temperature changing means changes temperature thereby changing the reflective value of the VO compound deposited on the temperature changing means.
