To be even more general, we can formulate an imaging condition
involving both space-shift and time-shift,
followed by image extraction at zero time:
However, the cost involved in this transformation is large,
so this general form does not have immediate practical value.
Imaging conditions described by equations
(6)-(7) are special cases of
for and , respectively.
