Abstract
The charge associated with an insulating sheet is monitored by scanning the specimen underneath a capacitive probe coupled to a detection system of very high input impedance. The charge distribution is displayed either on an XY recorder as a deflection modulation of the raster pattern, or with a cathode ray oscilloscope operating in the beam intensity modulation mode.Keywords
