ABSTRACT:
In manufacturing an optical device having a plurality of optical modulators and a color combining optical system, optical properties of a projection optical system are acquired, reference positions of the optical modulators are acquired, deviations of the optical modulators are calculated based on previously acquired optical properties, and the positions of the optical modulators are adjusted based on the deviations while detecting a combined light from the color combining optical system.
