摘要： PURPOSE:To facilitate the alignment of an optical axis, by a method wherein the fed-back beam of a Fabry-Perot interferometer formed of a sound receiving vibration plate and a 1/4 wavelength plate is re-converted to linear polarized beam which is, in turn, passed through a rod lens, a polarizing front preserving optical fiber and a polarizing beam splitter successively. CONSTITUTION:When a sonic wave is applied to a sensor head 2, a sound receiving vibration coated end surface 24r of a 1/4 wavelength plate 24 and the partial reflecting coated end surface 9r of the vibration plate 9 changes and the laser beam (i) fed back from the sensor head 22 comes to laser beam of which the intensity is modulated so as to be proportional to the displacement of the vibration plate 9 and the diffracted laser beam 1 thereof is incident on a beam receiving element 10 to be detected. By this method, the simultaneous alignment of five optical axes between two parts in the optical coupling of the sensor head and an optical fiber can be separated into the simultaneous alignment of three axes between two parts and that of two optical axes between two parts and the alignment of the optical axis becomes possible respectively independently and not only the alignment of the optical axis can be performed in an extremely easy manner but also a high SN ratio can be achieved with low loss.

摘要： PURPOSE:To detect the position of a magnetic tape during its run with high resolution by making a comparison between the outputs of two photodetectors which detect two parallel pieces of light beams passed outside both breadthwise end surfaces of the magnetic tape through slits respectively. CONSTITUTION:Parallel light beams (b) from a collimator lens 13 are wider than the magnetic tape 14, light beams (c) and (d) passed outside both breadthwise end surfaces of the tape 14 are guided to the slits 16a and 16b, and light beams (e) and (f) passed through their opening parts are guided to photodiodes 15a and 15b to obtain photoelectric conversion outputs (x) and (y). When the tape 14 is at the correct position, the outputs (x) and (y) become equal and the output (z) of a comparator 17 becomes zero, so that a servo device 18 does not operate. If the tape 14 is displaced from the correct position, on the other hand, the output (z) is no zero and led to the device 18, which moves the tape 14 and fixes it at the correct position.

摘要： PURPOSE:To easily detect the traveling condition of a magnetic tape with high resolving power without contact by disposing two pairs of light emitting and receiving parts to the positions where said parts are shielded by the magnetic tape and the position where said parts are not shielded by the magnetic tape, respectively. CONSTITUTION:The light emitting diode and photodiode 10a and 11a for position detection are provided in the positions where the diodes are not shielded by the magnetic tape 4. The light emitting diode and photodiode 10b and 11b in proximity thereto are provided in the position where the diodes are shielded by the magnetic tape 4. The detection outputs of the diodes 11a, 11b are processed by a comparator 7. The traveling condition based on the position in the direction orthogonals with the traveling condition of the magnetic tape is thus detected easily with the high resolving power without contact and the position of the magnetic tape is feedback-controlled with highs accuracy.

摘要： PURPOSE: To attain a sound receiving diaphragm which has a high sensitivity and is superior in impulse resistance by vapor-depositing deposited layers on both faces of a diaphragm substrate consisting of a metallic foil and setting the optical thickness of the deposited layer on the laser light incidence side to a half of the laser wavelength.
CONSTITUTION: A diaphragm substrate 10 consisting of a nickel foil having specular surfaces has 2mm diameter ϕ
1 and 2μm thickness t
1 , and the first and the second deposited layers 11 and 12 consisting of a quartz glass are vapor-deposited to both faces of the substrate 10. The optical thickness off the first deposited layer 11 is set to a half of the wavelength of a laser light source. Though the first reflected light R
1 and the second reflected light R
2 are generated on the surface of the deposited layer and the boundary surface between the deposited layer and the substrate respectively by an incident light I from the laser light source, synthesized waves of lights R
1 and R
2 are emphasized because the layer thickness is a half of the wavelength, and the reflection factor is maximized to improve the sensitivity. This diaphragm is made thin because mica is not used, and the resonance frequency is reduced to improve the sensitivity, and the diaphragm is superior in the impulse resistance.

摘要： PURPOSE:To enable efficient transmission of the light output from a semiconductor laser generator by supplying the light output from an optical microphone via a condenser lens to an optical fiber. CONSTITUTION:An optical microphone is provided with a semiconductor laser generator 1, and oscillating diaphragm 6, a microlens 17 for condensing and an optical fiber 18. The luminous flux of the light output 8 of the optical microphone formed in such a way is radial and even if said flux is transmitted in this state by the fiber 18, just a part of the light output 8 can be transmitted with a large loss. Therefore, the light is condensed to one point by the lens 17 which is a convex lens. The condensed light is then transmitted by the fiber 18. The light is converted to electricity by a photodiode at the terminal of the transmission. The sound signal is thus converted to light and the direct transmission of such light is made possible and therefore the light output from the semiconductor laser generator is efficiently transmitted.
