Abstract/OtherAbstract:
We describe a feasibility study of a multiplexed holographic recording method onto a moving storage medium by using moving interference fringes caused by diffracted light beams that are generated from an acousto-optic deflector (AOD). The AOD, driven by amplitude-modulated electric signals, generates several diffracted beams with different frequencies because of Doppler shifting by AOD driving-frequency components. The interference between the beams results in a nonstationary light intensity distribution, i.e., a moving interference fringe. Its velocity is reduced by an image-reduction optical system, and the storage medium is moved at the same velocity as the fringe motion at the image-formation point. This compensates for a reduction of visibility with the movement of the medium, so a holographic recording onto a moving medium can be achieved. In addition, angular multiplexing is achieved by switching the AOD driving frequencies.
