Abstract
For electro-optical image conversion as well as for optical image processing by spatial filtering, a two-dimensional optical filter is provided which comprises a microstructured grid, the openings of which are designed as a matrix of windows, the windows being provided with electrostatically movable thin-film closures. The window openings are controlled by electrostatic charges which are provided by an electron beam. This matrix of light valves can preferably be used as a electro-optical converter as well as a Fourier filter in an optical computer.
