Fig. 3. Area scan and deflection shapes of the tympanic membrane (TM) in N.
pronuba. (A) Orientation image relating tympanal topography (left image)
to the position of the scanning lattice (right image). (B) Area scans of
tympanal deflections for three different frequencies. The deflections are
shown each time for four different phases along the oscillation cycle (see
also Movies 1–3 in supplementary material). Deflections are additionally
shown as profiles, looking at the tympanum from its side. Red indicates
positive displacement (or outward tympanal deflections), and green indicates
negative displacement (or inward tympanal deflections).
