The uses and limitations of the electrostatic probe for the measurement of charge densities on insulating surfaces are discussed. A development of the technique is described in which two important limitations have together been overcome: (i) The effects on the probe signal of charges on all points of the surface have been taken into account by means of a matrix inversion procedure. (ii) A robotic control system has been developed which enables the probe to follow and scan a wide range of axi… CONTINUE READING
