CONSTITUTION:When a mirror 12 is moved in a direction X by dx with the movement of a stage 1 at shown by dotted lines in the diagram, the stage is assumed to be shifted by -dh in the vertical direction. At the time, the output of a length measuring device 14 is L1' and the output of a length measuring device 15 is L2'+h', but the L1' is equal to L1+dx, the (h') is equal to (h) and the L2' becomes equal to L2+dx-dh because the stage is moved by the (dx) from the output L2 of the device 15 and is returned by dh. Accordingly, the output of an arithmetic unit 17 is L2'+h'-L1'=L2+h-L1-dh and is changed by the dh, in short, by the amount of vertically movement of the stage 1, compared with the output of the unit 17 prior to the movement of the stage 1.
