ABSTRACT:
A microceramic optical shutter includes a unitary ceramic body which has been formed with first and second internal cavities, a coil structure formed in the first internal cavity and a ferromagnetic stator formed in the second internal cavity and disposed in operative relationship with the coil structure. The unitary ceramic body being formed with a light aperture therethrough and having a recess; and a shutter drive mechanism mounted in the recess and in operative relationship to the stator and having a shutter blade which is movable between light blocking and light passing positions relative to the light aperture so that when a drive voltage is applied to the coil structure, in a first direction a field is created through the stator which provides a driving force to the shutter drive mechanism to move it to the light passing position and when the drive voltage is applied in the opposite direction to the coil structure the shutter drive mechanism moves the shutter from the light passing position to the light blocking position.
