Abstract: A method for manufacturing a film structure includes: a positional deviation amount detection process of detecting an amount of positional deviation related to a relative position of a second cured film formed on a rear surface of a film with respect to a first cured film formed on a front surface of the film; a relative position adjustment process of correcting a position or a rotation speed of a second transfer roll to adjust the relative position such that the amount of positional deviation detected in the positional deviation amount detection process is reduced; a first tensile force detection process and a second tensile force detection process of respectively detecting a tensile force of the film between a first pressurizing roll and a second pressurizing roll before and after the relative position adjustment process; and a tensile force adjustment process of adjusting the tensile force of the film such that the tensile force of the film detected in the second tensile force detection process approaches the tensile force of the film detected in the first tensile force detection process.

Abstract: An optical adjustment apparatus includes a measurement-light irradiation part that has a plurality of second optical fibers and emits, with timings different from each other, a plurality of lights having a single wavelength via the second optical fibers, an optical fiber block that holds exit-side end portions of the first and second optical fibers, a light detection part that receives and detects a plurality of reflected lights via the second optical fibers, a tilt calculation part that compares, with each other, variations with time of intensities of the respective reflected lights and calculates a tilt of the optical fiber block relative to the optical substrate, and a distance calculation part that calculates an inter-end surface distance between the optical substrate and the optical fiber block, based on a variation with time of an intensity of at least one reflected light.
