摘要： An optical system is fabricated in the form of one device, so that the simplified optical system is realized. A displacement is measured with a high resolving power utilizing an interference fringe. An interference measurement probe 2 receives a coherent light from a light source section 1, and divides the coherent light into a plurality of luminous fluxes. The interference measurement probe 2 emits a plurality of irradiation luminous fluxes at different angles. The plurality of irradiation luminous fluxes form an interference fringe and the interference fringe is irradiated onto an objective 8. A light receiving section 3 is disposed at a position where a reflection luminous flux from the objective 8 interferes, and receives an interference light reflected from the objective 8, thereby outputting a light receiving signal which is converted to an electric signal. A measurement section 4 performs processing for obtaining displacement of positions of the interference measurement probe 2 and the light receiving section 3 as well as displacement of the objective 8. A control section 5 is connected to a driving section 6, and controls the driving section 6 based on a measurement result of the measurement section 4, thereby making a stage 7 move in the Z-direction. On the stage 7, the objective 8 is mounted or provided.

摘要： An simlified optical configuration is acheved and, a direction discrimination function and a high resolving detection function are performed by one light receiving section. A TE mode emitted from an optical waveguide section 3 transmits through a beam splitter 5 and is guided to a measurement optical path. A TM mode emitted from the optical waveguide is reflected by the beam splitter 5 and is guided to a reference optical path. First and second ¼ wave plates 10 and 11 are inserted in the respective optical paths, and the TE and TM modes are acted by a ½ wave plate while travelling forward and backward on the reference and measurement optical paths. A reference light (TM mode) is reflected by a reference reflection section 8 and transmits through the beam splitter section 5. A measurement light (TE mode) is reflected by a measurement reflection section 9 and is reflected by the beam splitter section 5. By a polarization member 12, only direction components of the polarization member 12 are extracted from the TM and TE modes, and both waves interfere, whereby a displacement is measured by a displacement measurement section 7.

摘要： Provided is a signal formation apparatus for use in an interference measurement which is capable of achieving a simplicity of optical adjustments and a subminiature of the apparatus, as well as a reduction of an influence by a wavelength variation of a laser light to the utmost. A coherent light emitted from a light source section 1 is supplied to a light emission portion 3 via a connection section 2. The light emission portion 3 comprises a straight type incidence waveguide 32, a dividing waveguide 33, emission waveguides 34 and 35, and a phase modulation section 36, which are provided on an optical substrate 31. The light emission portion 3 performs a phase modulation for one of luminous fluxes and emits irradiation luminous fluxes while keeping the other luminous flux as it is. In an irradiation optical portion 4, these irradiation luminous fluxes are collimating and deflected, and irradiated onto a measurement spot of a scale section 5. In the scale section 5, the two luminous fluxes are diffracted into approximately the same direction and incident onto a light receiving portion 6. A light receiving portion 7 convert the received luminous flux to an electrical received signal, and a displacement of the scale section 5 can be obtained by a displacement measurement section 8, based on the received signal.
