Spatial light modulation device |
摘要 |
A spatial light modulation device of the type, in which information is written to a photoconductor by a light writing portion and read light impinging on a light modulator is reflected by a reflection portion. This spatial light modulation device is provided with a dielectric mirror mounted on a reflection surface of the photoconductor, which surface is opposed to the other surface on which write light is incident. The reflection surface of the photoconductor reflects lights having wavelengths near a wavelength at which the photoconductor has a maximum sensitivity. Thereby, the spatial light modulation device can have a high sensitivity.
