Structure for optical masking has an array of masking elements each designed to assume translucent and non-translucent states along with a device to maintain the translucent state of the elements.

摘要

An optical masking structure (1) has an array (2) of masking elements (3) for using the opening of an aperture blocked by a masking element to assume a translucent state and for using the closing to assume a non-translucent state. Positioning elements (5) place a moving actuator element (4) in a two-dimensional position in a plane parallel to the expansion of the array. An Independent claim is also included for a method for operating an optical masking structure.
