    • PROBLEM TO BE SOLVED: To reduce an optical route length in interference displacement measurement.
      SOLUTION: This system is equipped with a sensor head 105 and a measuring lattice 106. The sensor head is equipped with a light source 200 for providing a light beam, a splitter lattice for splitting the light beam into first and second measuring channels 400, 500, a first retroreflector and a second retroreflector 208 constituted so as to retroreflect the first and second measuring channels so as to be returned to the measuring lattice, a first detector array arranged so as to receive the first measuring channel, and a second detector array arranged so as to receive the second measuring channel. The measuring lattice is constituted so that each measuring channel is split into a first arm and a second arm on the first illumination path, and that the first arm and the second arm are recombined on the second illumination path.

    • A device for measuring the heat-seal position of a plastic film (4) being fed in a fixed direction and having a heat-seal part (18) where a mesh pattern of micro protrusions and recesses are provided on its surface. A light source (23) and an optical sensor (24) are opposed to the plastic film (4), and a shielding plate (26) is interposed between the optical sensor and the plastic film. The shielding plate (26) has a small hole or a narrow slit for passing light. Light is emitted from the light source (23), light reflected from or passing through the plastic film (4) is passed through the small hole or narrow slit of the shielding plate (26) and directed to the optical sensor (24), through which image recognition is performed using the reflected light. Micro protrusions and recesses on the surface of the heat-seal part (18) are detected from the variation of the image, and the heat-seal position of the plastic film (4) can be determined.

    • According to the present invention, in order to improve the accuracy of the absolute value of a wavelength of diffraction light in the diffraction grating, a gas absorption line resulting from an absorption cell 8 is used as a wavelength reference 8. When reference light is exited from a light source 7 in a wavelength reference light source 1, the reference light is transmitted to a diffraction grating 2 as transmitted light having a spectrum absorbing only light of a predetermined wavelength by the absorption cell 8 to allow it to be reciprocated in a predetermined angle range. The diffraction grating 2 produces a split light beam from the transmitted light from the absorption cell 8. The diffraction grating 2 splits the transmitted light from the absorption cell 8 to provide diffracted light and the diffracted light from the diffraction grating 2 is received by the reference light receiving unit 3. It is possible to, without being affected by a variation in the environmental condition, accurately know the rotation angle of the diffracting grating 2 from the diffracted light of the absorption line-existing waveform component received by the reference light receiving unit 3, that is, the rotation angle of the diffraction grating 2 at a wavelength at that time.
