When the two meet, the interference pattern produced, if captured on photographic film, has the ability to change a new reference beam into a new object beam.

Moreover, since the resulting interference pattern also depends on the waves' frequency, the same array can concentrate SAWs in different ways at different frequencies, working the liquid sample in different ways.

When the reflected object beam and the reference beam are recombined, they create an interference pattern that encodes the 3-D image.
