摘要： In a vortex shedder the rate of flow is determined from the rate at which vortices are shed from a bluff body normally incorporating flexible capacitor plates at its sides which produce a signal when each vortex is detected. In this flowmeter the bluff body is a mere solid body and the vortices are detected downstream with an unclad section of optical fiber the attenuation of which changes in the presence of a vortex because of the change of refractive index associated with a vortex.

摘要： A measuring system for measuring the position of an object comprises a laser (10), a laser interferometer (16), and a detector (24). A series of sensors for sensing environmental conditions are provided; the sensors may be attached to the object. The sensors transmit information back to a central control (46) via LED transmitter (54). The transmitter (54) is powered from a battery (56) which is in turn charged by transducing (with a solar cell) part of the power of the light beam (12) generated by the laser (10). The sensors may be temperature sensors, pressure sensors, humidity sensors, refractive index sensors, vibration sensors, or beam alignment sensors.

摘要： A touch-trigger probe is provided with a sensor (which may be a mirror (106), an optical fibre (206), or a bi-refringent element (307)) which changes state by vibrating or undergoing strain when a stylus connected to the probe contacts a workpiece. The sensor is typically provided on (in the case of the mirror (106)), or in (in the case of the optical fibre (206)) the stylus. The change of state of the sensor causes a change in the path length, polarization state, or intensity of light waves conveyed by the sensor. An interferometer may be provided to detect such changes. Other forms of electromagnetic waves may be used to the same effect.

摘要： In a fiber optic interferometric magnetic sensor or magnetic gradient detector a magnetic bias field is applied to a magnetically sensitized portion of an optical fiber by means which are driven by optical power whereby a completely passive sensor head arrangement may be achieved. In a magnetic gradient detector optical power from a high power laser (34) may be supplied via an optical fiber (35) to illuminate a solar cell 27 to whose electrical output terminals solenoids (25,26) are connected. A portion of a respective optical fiber (21, 22) which is magnetically sensitized, by for example bonding to a strip of magnetostrictive material (23, 24), is disposed inside each solenoid (25, 26).

摘要： A vortex flowmeter having a double bluff body arrangement whereby vortices are generated at a rate corresponding to the fluid flow velocity. The upstream body and the downstream body together interact with the fluid stream to generate vortices. The arrangement introduces a relatively low blocking factor in comparison to simple bluff body arrangements. Vortex sensors are located between the bodies and downstream of the second body a distance between three and five times the diameter of that body.

摘要： A system for determining the concentration of oil in a mixture of oil and water including an aligned photocell and a displaced photocell spaced therefrom to receive direct and reflected and/or refracted light through a scatter cell from a laser. A logarithmic amplifier is connected from the aligned photocell because a logarithm of the output thereof is a linear function. The displaced photocell output is essentially linear over a typical range above 200 parts per million (ppm). The output of the logarithmic amplifier is essentially linear below about 200 ppm. The linear portion of each output is combined by a switch when the logarithmic amplifier output passes through a selected threshold level.

摘要： Apparatus for detecting oil in water contained in a chamber, wherein a semiconductor laser directs infrared radiation into the chamber. The radiation is scattered and detected by one or more cells. The output of one cell controls the gain of an amplifier connected from another cell. In one arragement, the outputs of two cells are connected to a differential amplifier, and the output of the differential amplifier is gain controlled by the output of a third cell.
