ABSTRACT:
Exposure modulation (strobing) at a photoreceptor surface due to mechanical vibration of the photoconductor is eliminated by placing a filter with appropriate transmission characteristics in the optical path. The transmission characteristics necessary to achieve zero strobing include an incidence profile having a zero Fourier transform at the vibration frequencies.
