Claims
- 1. A thermal imaging transducer system comprising a segmented wedge of ferroelectric material responsive to infrared radiation, means for polarizing said wedge using a descending voltage, means to electrically read a signal out of said wedge using an ascending voltage of a polarity the opposite of said descending voltage, such that the system will be responsive to a thermal image.
- 2. The thermal imaging transducer system of claim 1 wherein said means to electrically read a signal out of said wedge includes at least one set of thermal image responsive electrodes and a set of thermally shielded reference electrodes.
- 3. The thermal imaging transducer system of claim 2 wherein said thermal image responsive electrodes are mounted to said wedge in a transverse direction at spaced longitudinal points.
- 4. The thermal imaging transducer system of claim 2 comprising plural sets of thermal image responsive electrodes and wherein the image responsive electrodes are mounted at distinct longitudinal and lateral points upon the surface of said wedge such that and wherein said means to electrically read a signal out of said wedge is electrically connected to said image responsive electrodes.
- 5. The thermal imaging transducer system of claim 4 wherein both said responsive and reference electrodes are mounted to the same surface of said wedge.
- 6. The thermal imaging transducer system of claim 5 wherein said ferroelectric material is a material having discrete voltage level response to infrared radiation.
- 7. The thermal imaging transducer systems of claim 6 wherein said ferroelectric material is Bismuth Titanate.
