Patent ID: 8091167

Claim:
An imaging device, comprising: a power source; a glass layer; and an electrostatic particle removal system associated with the glass layer and the power source, the electrostatic particle removal system comprising: an induction grid layer including a plurality of conductive pads, the induction grid layer configured to: polarize a plurality of neutrally charged particles located between the glass layer and the electrostatic particle removal system to form a plurality of polarized particles in response to the power source applying a first voltage to the induction grid layer; and alter at least some of the polarized particles from neutrally charged particles to negatively or positively charged particles without any coronal discharge in response to the power source applying a second voltage to the plurality of conductive pads; a field grid layer configured to provide an electric field for moving the charged particles; and a collector base configured to collect the charged particles moved by the electric field.
