Paper Abstract

The pyroelectric vidicon and its performance characteristics are briefly reviewed, and attention is centered on the Philips' method for generating a pedestal current. This is done by pulsing the cathode during the horizontal flyback period to a potential such that the beam emitted during that time will strike the target with an energy above the first crossover for TGS. Features of the pyroelectric vidicon which must be taken into account for selecting a camera are: signal currents of about two orders of magnitude lower than those in a conventional vidicon, tube electrode voltages, and pedestal current. Field tests with a camera system having an MRT of 0.3°C at 100 TVL with f/1.0 germanium optics showed the usefulness of this relatively low-priced, uncooled, TV compatible, thermal imager. Potential improvements could result in an MRT of 0.3°C at 280 TVL.
