HOLOGRAM RECORDING DEVICE AND PROGRAM

PROBLEM TO BE SOLVED: To provide a hologram recording device and a program capable of recording each of a plurality of holograms so as to make the intensity of diffraction light constant regardless of the positions of multiple light emitting elements on a substrate in the width direction.SOLUTION: There is provided a hologram recording device that comprises: light irradiation means which irradiates a hologram recording layer arranged on a substrate having a plurality of light emitting elements with signal light and reference light; movement means moves the hologram recording layer relatively to the light irradiation means; measuring means which measures the position and emission intensity of each of the plurality of light emitting elements before recording a hologram; acquisition means which presets an irradiation position of the signal light in a width direction of the substrate and acquires recording conditions for recording each of a plurality of holograms so as to make the intensity of diffraction light constant in accordance with the measured position and emission intensity of the light emitting elements; and control means which controls the light irradiation means and the movement means so that each of the plurality of holograms is recorded sequentially in accordance with the acquired recording conditions.
