摘要： An optical system for producing an optical output having a beat frequency. The shifter has a beam splitter for splitting a laser radiation generated by a laser source, into a first and a second laser beam, and includes an acoustooptical modulator for deflecting the first laser beam and thereby changing the frequency of the first laser beam. The shifter further has an optical-path changing device such as a convex lens or parabolic reflector for changing an optical path of the first laser beam deflected by the acoustooptical modulator, into parallelism with the optical axis of the changing device. The focal point of the optical-path changing device is located at a point of emission of the deflected first laser beam. A mixer is provided for mixing the deflected first laser beam with the second laser beam, thereby causing an interference between the first and second laser beams, to produce a beat frequency equal to a difference between the frequencies of the first and second laser beams.

摘要： Method and apparatus for detecting the roughness or undulation of a subject surface, by using a light beam which is converged on the subject surface by an object lens and which is reflected by the subject surface. A relative position between the object lens and the subject surface in the direction parallel to the optical axis of the lens is controlled so that the measuring light reflected by the subject surface has a plane wave. On the other hand, an amount of relative displacement between the object lens and the subject surface is detected, based on a heterodyne interference between a light beam reflected by a stationary mirror and a light beam reflected by a movable mirror which is moved as the relative position is changed. The surface condition is detected based on the amount of relative displacement between the object lens and the subject surface which is detected when said plane wave of said measuring light beam is obtained.

摘要： A rotary encoder includes a laser device which emits a laser beam having beats caused by superposition of a parallel wave and a vertical wave, which have mutually different frequencies and whose oscillating surfaces are normal to each other. A part of the beating laser beam is led to a first detector where the beat frequency of the original laser beam is detected. The remaining laser beam is split into the parallel and vertical waves by a splitting/irradiating device, and the parallel wave is irradiated onto a predetermined position of the rotational member and is scattered or reflected upon Doppler shifting attendant to the rotation of the rotational member. The scattered or reflected parallel and vertical waves are led to a synthesizer where both waves are synthesized to provide a laser beam with beats. The synthesized laser beam is led to a second detector where the beat frequency of the laser beam after being Doppler shifted is detected. The thus detected beat frequency and the beat frequency detected in the first detector are supplied to an arithmetic unit. The arithmetic unit computes a rotational angle of the rotational member in accordance therewith.

摘要： An optical surface roughness measuring device for measuring roughness of a surface of a subject in a non-contacting manner. The apparatus includes a laser device for producing two linearly polarized laser beams which has mutually perpendicular polarization planes and different frequencies, and an optical device adapted to receive the two linearly polarized beams, converge one of the two laser beams so as to irradiate a first reading spot on the surface of the subject, convert the other of the two laser beams into parallel rays of light, and irradiate a second reading spot on the surface with the parallel rays of light of the other laser beam such that the second reading spot is aligned with the first reading spot and has a diameter sufficiently larger than that of the first reading spot. The surface roughness is measured based on a detected change in a beat frequency of the two laser beams reflected by the first and second reading spots. Alternatively, the two beams may be converged by a converging lens device at two spaced-apart points of the subject surface. In this case, an optical device includes an arrangement for establishing an angle of inclination between the directions of incidence of the two beams upon the converging lens device.

摘要： An optical waveguide element includes an optical waveguide formed on a light-transmissive dielectric substrate and having a higher refractive index than the refraction index of the substrate, the optical waveguide including a region having an effective refractive index which varies nonlinearly in a direction in which a light wave is propagated through the optical waveguide. The light wave guided through the optical waveguide enters the region, in which the angles of incidence and reflection of the guided wave at the boundary between the region and the substrate is gradually reduced due to the variation in the effective refractive index. When the angles of incidence and reflection of the guided wave becomes smaller than a critical angle, the guided wave is emitted out of the waveguide. Since the effective refractive index changes nonlinearly with respect to the distance the guided wave is propagated, the light emitted into the substrate tends to converge at a point, and the beam pattern of the emitted light is spread less.
