Abstract
A computer-readable signal bearing medium (10) has components (11, 21, 31) which act via a data processor (86) in an imaging system having an acoustic energy source (81) and a birefringent detector (84, 70) to record first data (14) from a first portion (61) of an object (60), the first portion attenuating first acoustic energy (12) at least part way to a first attenuation maximum (13, 43) along a first acousto-optic response (41) of the birefringent detector; to record second data (24) from a second portion (62) of the object, the second portion attenuating second acoustic energy (22) at least part way to a second attenuation maximum (23, 53) along a second acousto-optic response (51) of the birefringent detector; combines the data (32), and outputs a result.
