Abstract:
A scan corrected vidicon camera apparatus utilizing a spatial reference filter with an array of slits that is fitted directly on the faceplate of a vidicon tube. The spatial reference filter is used in conjunction with perturbations that are injected into the vertical and horizontal sweeps. The resultant video waveform is correlated in a microprocessor unit to linearize the respective sweeps.
