<p>[Problem] To provide exposure equipment capable of preventing speckle from standing out in an optical image formed on a photosensitive medium, and effectively suppressing the occurrence of unevenness in the brightness within a prescribed region. [Solution] The exposure equipment (10) is provided with an optical element (50), a lighting device (60), and a spatial light modulator (30). Using a scanning device (65), coherent light is scanned across a hologram recording medium (55), and the coherent light coming from the hologram recording medium (55) irradiates the spatial light modulator (30), which overlaps with a prescribed region (LZ). In addition, a photosensitive medium (15) is positioned adjacent to the spatial light modulator (30); hence, using a very simple configuration, it is possible to guide coherent light to the photosensitive medium (15) without causing speckle to stand out.</p> |
