1. A panel of controllable radiation transmissivity, comprising:
a plurality of rotatably mounted radiation-blocking members, each of said members having at least one portion which is substantially
opaque, and
means for rotating said radiation-blocking members, said radiation-blocking members, when rotated, being adapted in at least
one angular position to substantially block the passage of radiation through said panel, and in a plurality of other, selectable,
angular positions, to provide a plurality of differing radiation transmissivities,
characterized by a plurality of substantially transparent tubular cells, said radiation-blocking members being mounted in
at least some of said tubular cells, and
means for rotating said radiation-blocking members inside said tubular cells.
