摘要
It is crucial to understand the effects of random mechanical vibration on holographic data storage system, but such effects have not yet been formalized. Therefore, we developed a generalized formalization of vibration effects using a concept of time-averaged holography. Normalized intensity as a function of a statistical measure of vibration waveforms is simulated by simple harmonic oscillation, then normalized intensity is predicted well even for random vibration waveforms. Servo and mechanical systems will be designed solely by specifying the required signal level, which enables efficient product development.
