    摘要： A coupler for coupling the end of an optical signal transmission line comprising at least one optical waveguide, to a solidstate converter device such as a light emitting diode or a photosensitive diode according to the case, the converter device presenting a refractive index N3 higher than the refractive index N1 of the optical waveguide. The coupler comprises a transparent matching medium having at least a refractive index N4 of value intermediate between the values N1 and N3 and forming a thin parallel faced plate whose maximum thickness is determined on the basis of the numerical aperture of the guide.

    摘要： A sensor system for determining the spatial location of radiation relative to the sensor including three unit sensors each having a cylindrical optical lens and a linear array of photosensitive elements positioned in the focal plane at a fixed angle with respect to the longitudinal axis of the lens. Each lens determines substantially a plane of radiation passing through the source. The unit sensors are arranged to define three separate planes having the radiation source being detected as common point. The detected signals are processed to identify respectively the serial position of the elements activated by the focused radiation. Ancillary calculating means calculates the location of the source from the serial position information. By detecting a plurality of sources coupled to a movable body, the present invention enables the user to continuously determine the direction of a fixed axis of the movable body.

    摘要： An arrangement which enables the presence in an observed field of a light source whose radiation spectrum is known to be detected with a high signal to noise ratio. It includes an acousto-optical tunable filter controlled to scan through the expected spectrum of the source periodically and preferably linearly. The photo-detected signals are processed by a high-pass filter which removes the D.C. component due to ambient interference radiation and provides a periodic signal which correspond to the observed light source. The arrangement applies, in particular, to the angular location of luminous targets.
