摘要： A position detector includes a diffraction grating provided on the surface of an object, an illumination system for illuminating the diffraction grating, a detection system for detecting diffracted light diffracted from the diffraction grating, and a processing system for detecting positional information relating to the object. The illumination system emits a first pair of beams which are diffracted by the diffraction grating and interfere with each other, and emits a second pair of beams which are diffracted by the diffraction grating and also interfere with each other. The first pair of beams are incident upon the diffraction grating along a plane extending in a first direction in which the diffraction grating extends. The second pair of beams are incident upon the diffraction grating along a plane extending in a second direction in which the diffraction grating extends. The first and second directions are different from a grating line direction. The detection system detects the interfering light and generates first and second beat signals therefrom. The processing system detects positional information with respect to the first direction from the phase state of the first beat signal and with respect to the second direction from the phase state of the second beat signal.

摘要： An optical device is composed by sandwiching a deformable member between sandwiching members. The deformable member has a shear modulus decreasing toward the inside. The deformable member may be a combination of a core and a coating with different shear moduli or a single body having a continuoudly decreasing shear modulus. The sandwiching members may be a flat plate either transparent or opaque or a lens with or without reflecting film. Because of inner soft and outer hard elastic nature of the deformable member, the sandwiching members can easily change their relative position to change an optical path and an imaging position of the optical device with good durability.
