An expanded-range pintle valve comprising a plurality of stages. The switch circuit outputs a first image signal generated by the main path or a second image signal generated by the sub path by switching therebetween, and the first judging circuit outputs a first motion signal in accordance with an output of the motion region detection circuit. An integrator circuit generates a sensed voltage responsive to the output current. The tiling scheme of the present invention effectively increases the port count of a three-dimensional optical cross-connect switch without increasing the angular deflection required to access all of the pixels in the switch.
