Abstract
A target for ultrasonic camera comprising, applied to a substrate, a pyroelectric retina covered, in the present example, with a layer which absorbs incident ultrasonic waves; the temperature rise due to said absorption produces in the retina a charge relief read out by means which depend upon the selected device, for example an electron beam as in the case of the known pyroelectric targets.
Claims10
A target for an ultrasonic camera device, characterised in that it comprises, a substrate which is exposed to incident ultrasonic waves, and applied to said substrate a retina made of a pyroelectric material and means for transforming the energy of said ultrasonic waves into thermal energy transmitted to said retina.
