摘要： A polarimetric directional field sensor comprises an emitter and receiver (1) of measurement signals, connected by optical fibres (2, 2a, 2b) to a portable probe (3). The probe (3) comprises an optical element (11, 13) sensitive to the field to be measured and means (9, 20) for polarizing the measurement signal. The optically sensitive element (11,13) is in the form of a birefringent crystal having a crystalline structure which provides at least one plane in which the induced birefringence is modified by a single component of the field to be measured. The crystal is cut and oriented in the probe so that the direction of propagation of the optical measurement signal inside the crystal is normal to this plane, the polarizing means (9, 20) being oriented at 45° to the orthogonal axes in which the crystal's refractive indices are modified by the desired component of the field.

摘要： A new rapid optical specific absorption rate (SAR) system is disclosed. The rapid optical SAR system has ability to measure and map the power deposited in a flat phantom or other phantom filled with a transparent simulant fluid. Absolute rates of temperature increase in the phantom by photo thermal techniques are measured. For example, the temperature increase and gradients in the phantom bend the path of a laser beam, which may be aimed at a position sensitive detector. The spatial SAR may be mapped and SAR differences between different telephones and telephone orientations, for example, can be distinguished. The system is non-invasive and non-perturbing of the SAR distribution in the phantom, can measure at locations up to the interior surface of the phantom, and provides thermally-based SAR measurements that do not necessarily require constant calibration.

une source lumineuse de longueur d'onde variable et commandable,
un capteur électro-optique dont un élément est constitué d'un matériau optique biréfringent, dont l'une des faces est réfléchissante,
une fibre optique à maintien de polarisation placée entre la source lumineuse et connectée au capteur de façon à orienter l'axe de polarisation du faisceau émis dans une direction faisant un angle sensiblement égal à 45° par rapport aux axes diélectriques propre de la partie active du capteur,
un élément photo-détecteur pour convertir le faisceau lumineux réfléchi par le capteur en un signal électrique proportionnel à la puissance lumineuse reçue,
des moyens de contrôle permettant de faire varier la valeur de la longueur d'onde λ émise.

Le dispositif selon l'invention asservit le point de fonctionnement du capteur électro-optique en faisant varier la longueur d'onde émise par la source en fonction de la puissance optique reçue par le photodétecteur.
L'invention trouve son application dans tous les domaines où la mesure ponctuelle ou la cartographie dans un espace donné espace d'un champ électrique ou électromagnétique revêt une certaine importance.

摘要： An electric field sensing system is characterized so that a signal processor may derive an output representative of an electric field intended to be measured, particularly established by high voltage on a power line, with enhanced accuracy. Characterizing parameters may be derived from signals representative of a pair of light waves derived from a light wave exiting an optical electric field sensing element in a electric field sensing head spatially positioned in the high voltage environment.
