ABSTRACT:
A battery-powered corona discharge photography device for holding a photographic recording medium adjacent an electrode, with a specimen in contact with the recording medium. A highly regulated voltage source is coupled by a voltage step-up circuit to a capacitor for storage of an increased level voltage. A silicon controlled rectifier is triggered by a pulse generator to discharge the capacitor, causing a voltage pulse across a transformer primary. Once the pulse generator is activated, it generates a series of pulses of a number determined by the setting of a switch, and so a like series of high voltage electrical pulses is generated across the transformer secondary, and this secondary is connected to the electrode. Either of two transformers can selectively be utilized, to provide selectivity in the frequency characteristics of the high voltage electrical pulses. Means are also provided for reversing the polarity or adjusting the voltage level of the high voltage electrical pulses.
