Abstract
An electrostatic shutter includes an input window, an electrical contact connected to the voltage source, a metallized polymer scroll having one end electrically connected to the electrical contact, an electrically and thermally conductive heat sink selectably connected to the voltage source and so that a potential difference exists between the electrical contact and the heat sink and an electrical insulator covering the heat sink. When a sufficient voltage potential exists between the scroll and the heat sink, the scroll unrolls so that the scroll is in direct contact with the input window and thermally coupled to the heat sink through the insulator and the input window.
