On the other hand, the laser light 50 introduced in the diffuser 22 is diffused at random by the diffuser 22 to form reference light 200 having a speckle pattern. The signal light 100 and the reference light 200 are condensed on the hologram recording medium 24 by the lens 23. In this instance, interference fringes of the signal light 100 and the reference light 200 are recorded in the hologram recording medium 24.
