Abstract:
An apparatus for manufacturing an optical device, the apparatus performing mutual position adjustment of each of a plurality of light modulators and fixing each of the light modulators to a light-incident surface of a color-combining optical system, in order to manufacture the optical device including the plurality of light modulators, each of which modulates each of a plurality of colored light rays according to image information, and the color-combining optical system to combine the colored light rays modulated in the light modulators, the apparatus comprising:an adjusting light source device including a plurality of light sources to supply colored light rays to be modulated to each of the light modulators, the light sources including self-light-emitting elements; a luminous flux detector to detect a luminous flux emitted from the adjusting light source device and passed through each of the light modulators and the color-combining optical system; and a position adjusting device to adjust the position of each of the light modulators based on the luminous flux detected by the luminous flux detector.
