ABSTRACT:
Light from a collimated light source which is incident on a birefringent detector at a predetermined optimum angle interacts with the birefringent detector and is viewed by an imaging transducer in order to produce an image which shows changes in the birefringence of the birefringent detector caused by acoustic energy which has interacted with an object, the image thus showing heterogeneities in the object.
