The estimation of the cathode current density of CRTs from cathode image by means of TV camera and micro-processing technique is proposed. It is supposed that the relation between the analog current and the summation of the digital current value of picture element is equal. Then the cathode current density can be obtained from the processed emission current density distribution curve.
