MANUFACTURE DEVICE FOR OPTICAL DEVICE, POSITION ADJUSTING METHOD, POSITION ADJUSTING PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a manufacture device for an optical device by which an optical modulator is accurately positionally adjusted. SOLUTION: A controller 40 constituting the manufacture device includes: a pattern forming part 433 making the optical modulator form a one-dot pattern where only one display pixel is set to prescribed brightness in an adjusting area used for position adjustment out of the image forming area of the optical modulator thereon; a center-of-gravity position calculation part 4,362A calculating the position of the center of gravity in a corresponding area corresponding to a display pixel in a picked-up image picked up by an imaging apparatus on the basis of each luminance value of every pixel in the picked-up image; a deviation calculation part 4,362B calculating deviation between the position of the center of gravity and a preset reference position; and a fine adjustment control part 4,362C positioning the optical modulator at the prescribed position relative to a color synthesizing optical device by driving and controlling a position adjusting device on the basis of the deviation.
