Abstract :
The feasibility of aberration multiplexing in microholographic recording was investigated through a numerical simulation. The multiplexing is performed by forming multiple microholograms at the same position by changing the aberration of recording beams and selectively reproducing each of multiple microholograms by changing the aberration of a readout beam. The simulation showed that multiplexing of more than 10 bits would be possible by combining the spherical, coma, and astigmatic aberrations.
