The first spatial light modulator has a phase modulation plane on which a kinoform for performing intensity modulation is displayed, and generates modulated light P2. The pinhole member has a light passing hole for letting a first-order light component of the modulated light P2 pass therethrough, and blocks a zeroth-order light component of the modulated light P2. The second spatial light modulator has a polarization modulation plane that controls the polarization state of the modulated light P2 incident on the polarization modulation plane through the light passing hole of the pinhole member, and generates modulated light P3.
