    摘要: A three-dimensional measurement method and device are intended for fast and accurate measurement of large objects such as vehicles. The method includes the steps of determining approximate measurement positions of a shape measurement sensor; positioning the sensor at successive approximate measurement positions to read off the shape of surface portions of the object represented by points on the object whose co-ordinates are expressed in a system of axes fixed relative to the sensor; identifying accurate positions of the sensor at the approximate measurement positions relative to a predetermined fixed system of axes; and converting the co-ordinates of the points of the surface portions expressed in the system of axes fixed relative to the sensor into co-ordinates expressed in the fixed system of axes on the basis of the identified accurate positions of the sensor.

    摘要: The optoelectronic method and system provides for remote detection of physical magnitudes by multiplexing and demultiplexing signals from a plurality of sensors. The system utilizes a single source of incoherent light which illuminates via optical fibers a plurality of sensors associated with encoding devices. Periodic modulation on the light transmitted by each sensor is accomplished at a frequency which is characteristic of the sensor in question. Demultiplexing is provided for demodulating the signals from the various sensors by a Fourier transform, and for identifying each signal by its characteristic modulation frequency.

    摘要: An optical device (12) includes a front surface located on the side of the sample to be observed and a rear surface oriented towards the elements for acquiring (18, 19) an image or a user. It further includes a combination of four aligned lenses. The lenses are arranged in the following sequence from the front rearwards: a plano-convex lens (28), a convexo-concave lens (30), a plano-concave lens (32) and a biconvex lens (34). The plano-concave (32) and the plano-convex lenses are respectively such that they each have a substantially planar surface and a concave surface or convex surface respectively. The invention is applicable to a cell analyzer.

    摘要: An optoelectronic apparatus for the remote measuring of a physical magnitude which comprises two light sources emitting luminous fluxes centered on two different wavelengths and means for controlling the alternate operation of these light sources. A sensor is provided for receiving the luminous flux emitted by the respective light sources and causing a periodic spectral modulation of the luminous flux a frequency depending on the value of the physical magnitude to be measured. An analysis means is provided for analyzing the luminous flux transmitted by the sensor, the analysis means being of the static type and including a birefringent element which is tuned to the sensor and produces an optical path difference close to that produced by the sensor.
