Title (EN) PROCESS AND DEVICE FOR MEASURING A DISTANCE BY TELEMETRY
(FR) PROCEDE ET DISPOSITIF POUR LA MESURE D"UNE DISTANCE
Abstract: front page image
(EN)A process and a device for measuring a distance are described using an opto-trigonometric arrangement and a photoelectronic positioning determination. The target (2) is irradiated by means of light radiation (S1) and the impact point (T1) is optically represented on a linear photodetector (5) by means of an oblique angle (B) to the irradiation direction. The spatial position (d2) of the impact image is determined by means of an electronic scanning by the photodetector and from there, the distance (D1) from the target is measured by means of trionometric relations. Preferred alternatives are specially intended for measuring short distances and hollow profiles.
(FR)Un procede et un dispositif pour la mesure d"une distance utilisent une disposition optotrigonometrique et une determination de position photoelectronique. Le but (2) est irradie au moyen d"un rayonnement lumineux (S1) et le point -- d"impact (T1) est represente optiquement sur un photodetecteur lineaire (5) au moyen d"un angle oblique (B) par rapport a la direction d"irradiation. On determine la position spatiale (d2) de l"image d"impact au moyen d"un balayage electronique du photodetecteur et de la, on calcule l"eloignement (D1) du but au moyen de relations trigonometriques. Des variantes preferentielles sont specialement destinees a la mesure de courtes distances et de profils creux.
