摘要： An optical system for recording n information signals on a photosensitive tape in the form of a discontinuous track made up of parallel track sections by means of n light beams having a two states modulated intensity, being simultaneously deflected by an acousto-optical deflector and focusing on the tape in the form of n equidistant spots aligned in a direction x. The combination of the deflection and a translation movement of the tape produces a scanning movement of said n spots in a direction perpendicular to x. The same system is made for the reading of the information transcribed on the tape, the beams being then not modulated, by means of photodetector means which receive the light emerging from the tape and provide information signals in relation with the physical modifications obtained on the tape during the recording.

摘要： The invention relates to a method and a device for the optical reading of information recorded on a support along a track in the form of diffracting elements. A diffraction pattern comprising a luminous central spot centered on the section of the track to be read and alternately dark and bright adjacent fringes is projected onto the support, the dark fringes adjacent to the central spot coinciding with the track sections in the neighborhood of the track section to be read. To that effect a pupil limited by two edges which are parallel to the direction of travel of the track is utilized, this pupil being placed against the reading objective.

摘要： The invention relates to an optical reading device, for the read out of data carried by a reflecting support, wherein the source is a non-polarized laser of which the exit surface is reflective; the optical noise due to the reflection of the incident wave at the support is partially suppressed by inserting between the last partially polarizing and/or birefractive element and the data carrier a quarter wavelength plate which optically decouples the incident wave and the return wave. The optical noise is thus limited to the beats between the incident wave and the return wave reflected a second time by the support.

摘要： The invention relates to the focusing of an optical system by variation of the radius of curvature of a reflecting element, comprising two prepolarized thin plates of piezoelectric material which are joined together and each of which carries an electrode, the outer surface of one of the two thin plates being made reflective. An electrical signal characteristic of the correction to be made is applied between the two electrodes and produces a variation in the radius of curvature of the thin plates. This reflecting element is used in an optical system of the Cassegrin type or as a reflecting mirror.

摘要： Unlike customary vibrating mass gyros which operate by exciting a first fundamental mode of vibration of the vibrating mass and by detecting the effect of the Coriolis force on a second fundamental mode of vibration of the vibrating mass orthogonal to the first mode, this gyro operates by giving its suspended mass a circular motion alternately in the forward and reverse directions and by deducing the gyrometric effect from the difference between the apparent frequencies of the circular motion of the suspended mass in one direction and in the other. This allows a considerable reduction in the drafting of the heading measurement obtained with this type of gyro.

摘要： The invention relates to a method and system reading data recorded in the form of tracks on a magnetic recording medium. The recorded data is read by a row of read heads greater in number than a number of data tracks. The system of the invention does not require the read heads to follow the data tracks when reading recorded data, and allows a magnetic tape to be read even if the positions of the data tracks relative to the read head positions are unknown. The reading system of the present invention finds particular application in the area of reading high density recorded magnetic tapes.
