Abstract: A method for connecting an optical waveguide includes: adjusting an inclination of an optical fiber block with respect to substrate (10), the optical fiber block including through-passage (34), and the substrate including spacer (60) surrounding light input part (12), by holding and bringing optical fiber block (20) into contact with the spacer, and then releasing the optical fiber block; supplying adhesive (70) to outside of the spacer on the substrate; aligning the optical fiber block holding an optical fiber, with respect to the light input part, to maximize intensity of light output from the substrate; compressing the spacer by pushing the optical fiber block including the through-passage toward the substrate; and curing the adhesive, with the spacer compressed.

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 measuring device includes: a laser light source that emits first light having a first wavelength; an image capturing unit that emits second light having a second wavelength different from the first wavelength; a separating unit that receives the first light and the second light to direct the first light and the second light toward an object to be measured, and receives reflected light from the object to be measured to separate the reflected light into first reflected light based on the first light and second reflected light based on the second light; a light receiving element that receives the first reflected light separated by the separating unit; and a calculating unit that calculates a yawing angle and a pitching angle of the object to be measured based on a light receiving result of the light receiving element, in which the image capturing unit captures an image of the object to be measured by receiving the second reflected light separated by the separating unit, and the calculating unit calculates a rolling angle of the object to be measured based on an image capturing result acquired by the image capturing unit.

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.
