Abstract: |
|||
| The invention provides a hologram recording method and a hologram recording device. The invention proposes a hologram recording method that includes: generating signal light by superimposing a periodic intensity distribution or phase distribution on an intensity distribution of light that expresses binary digital data as a light/dark image; Fourier transforming the signal light; illuminating Fourier transformed signal light and reference light simultaneously on an optical recording medium; and recording the signal light as a hologram. | |||
