Patent ID: 7102730

Claim:
An exposure device comprising: a light source which emits a light beam for exposure; a spatial light modulation device at which a plurality of modulation elements, which respectively change light modulation states thereof in accordance with control signals, are two-dimensionally arranged, the spatial light modulation device being for modulating the light beam, which is incident at the plurality of modulation elements from the light source, at each of the modulation elements; a microlens array at which a plurality of microlenses are two-dimensionally arranged with a pitch corresponding to the plurality of modulation elements, the microlens array being for condensing light beams, which have been modulated by the modulation elements, at the respective microlenses; a shift amount detection section for detecting an offset amount of relative positions of the light beams which have been modulated by the modulation elements and the corresponding microlenses; and a position adjustment section which finely adjusts position of at least one of the spatial light modulation device and the microlens array on the basis of the detected offset amount.
