    • An optical recording device includes a light source, a spatial light modulator, a correcting optical system and a light guiding section. The spatial light modulator includes plural pixels, a signal light region that displays a signal light pattern, and a reference light region that displays a reference light pattern. The spatial light modulator modulates and outputs incident light for each pixel in accordance with a display pattern. The correcting optical system includes a pair of axicon lenses that correct the emitted light from the light source so as to flatten the light intensity distribution thereof on an irradiated surface of the spatial light modulator. The light guiding section guides the corrected light to the spatial light modulator. The signal light and the reference light are irradiated onto an optical recording medium simultaneously and a hologram is recorded into the optical recording medium.
    • 光记录装置包括光源,空间光调制器,校正光学系统和导光部。 空间光调制器包括多个像素,显示信号光图案的信号光区域和显示参考光图案的参考光区域。 空间光调制器根据显示图案调制并输出每个像素的入射光。 校正光学系统包括一对旋转透镜,其校正来自光源的发射光,以使其在空间光调制器的照射表面上的光强度分布变平。 导光部将校正后的光导向空间光调制器。 信号光和参考光同时照射到光学记录介质上,并将全息图记录到光学记录介质中。
