Your code does not compile but this version works as expected:

   ImagePlus imp = IJ.getImage();
   ImagePlus imp2 = new Duplicator().run(imp);
   IJ.log("1-> "+imp.getCalibration() + " - " + imp.getCalibration().scaled());
   IJ.log("2-> " + imp2.getCalibration()+ " - " + imp2.getCalibration().scaled());

This is the output:

1-> w=0.02, h=0.02, d=0.02, unit=mm, f=20, nc=null, table=null, vunit=Gray Value - true
2-> w=0.02, h=0.02, d=0.02, unit=mm, f=20, nc=null, table=null, vunit=Gray Value - true
