Optical device with magnetically operated micro-shutters or micro-mirrors

摘要

An optical device comprises a substrate (2) and a matrix of micro-shutters or micro-mirrors (5), in the form of thin-film laminas, each of which having one end connected to the substrate (2) and the other end free. Each lamina is free to move from one curved, or resting, position, in which its free end is at a distance from the substrate (2), and a straightened-out condition, in which it adheres to the substrate. The displacement is obtained by magnetically operated control means.
