ABSTRACT:
A wedge of ferroelectric material is used as a thermal imaging transducer by plating a multiplicity of signal generating electrodes to the surface of the ferroelectric wedge. The wedge is electronically polarized using a descending voltage and thermal images are read out of the transducer using an ascending voltage ramp of opposite polarity from the polarizing voltage. Readout is obtained without requiring mechanical panning or thermal image interruption even if the subject is stationary.
