Abstract
An arrangement for chopping a collimated beam of light traveling in an initial path, includes a flexible mirror which reflects substantially all of the light from the initial path into an auxiliary path in a first configuration thereof. The flexible mirror is deformed by a magnetodistortive actuator from its first configuration to a second configuration in which it disperses the light reaching it in such a manner that all but a minute fraction of the dispersed light propagates outside the path. Further propagation of the light that is reflected by the flexible mirror to the outside of the auxiliary path along the auxiliary path is blocked by an aperture plate having an apeture through which all of the light reflected by the flexible mirror passes when the flexible mirror has its first configuration.
