ABSTRACT:
An inline type speckle multiplexed hologram recording apparatus and method is disclosed which can condense signal light and reference light in a sufficiently overlapping relationship with each other on a hologram recording medium without using a lens having a large aperture and a wide angle of view. A signal light region and a reference light region are displayed on a spatial light modulator, and laser light is intensity modulated with recording data displayed in the signal light region to produce signal light while the laser light having passed through the reference light region is used as reference light. The signal light and the reference light are diffused by a diffuser and then condensed in an overlapping relationship with each other on a hologram recording medium by a lens such that interference fringes produced thereby are recorded in the hologram recording medium.
