A phased-array light telescope includes at least two non-obscured light subtelescopes. The read circuit selects one determination level from among a plurality of determination levels corresponding to a position of a magnetoresistive effect element in the cell array and uses the selected determination level to perform reading of the data. The system also comprises a second outer layer and a second device layer comprising a second set of MEMS devices, wherein the second device layer is bonded to the second outer layer.
