Optical disc jitter generator and its calibration system

摘要

Jitter is one of the most important parameters for optical disc evaluation. This paper presents a design of a simulated optical disc jitter generator based on a sinusoidal frequency-modulated (FM) signal. An innovative method is proposed to calibrate the jitter generator based on the Bessel-zero method. Finally, measurement uncertainty of the calibration system is described. The results of theoretical analysis and experiments indicate that the expanded uncertainty of measurement is 0.13percent in CD mode, and 0.18percent in DVD mode, k velence 2.
