      Design featuresFabrication–integration issues, cost Misregistration issues
      Rotating element● Robust ● Relatively small ● Not suitable for dynamic scenes ● Easiest to implement ● Inexpensive ● Scene and platform motion ● Beam wander not a problem or removed in software ● Misregistration is linear
      Division of amplitude (multiple FPAs) ● Simultaneous acquisition ● Large system size ● High mechanical flexibility and rigidity required ● Expensive ● Large ● Must register multiple FPAs ● Misregistration can be fixed ● Can be nonlinear
      Division of aperture (single FPA) ● Simultaneous acquisition ● Smaller size ● Loss of spatial resolution ● Expensive ● Fixed misregistration ● Can be nonlinear
      Division of focal plane● Simultaneous acquisition ● Small and rugged ● Loss of spatial resolution ● Fabrication difficult ● Alignment difficult ● Very expensive ● IFOVs misregistered ● Requires interpolation ● Fixed registration
      Coboresighted● Simultaneous acquisition ● Best used at long ranges ● Easy integration ● Expensive ● Misregistration not as stable
