Axial imaging necessitates loss of lateral shift invariance.
We conjecture that the lateral shift invariance of an imaging system must be limited if axial imaging capability is desired. We develop shift-invariance and depth-resolution metrics and demonstrate the trade-off in simple representative systems.
