Abstract
(EN) A detector and a detection method which can detect various objects such as blood vessels with a high sensitivity and a high accuracy based on a novel principle. The detector consists of m (m is an even number of 4 or above) electrodes for generating m electric charges rotationally symmetrical about at least one straight line, with a sum of charge amounts of these electric charges being nearly zero, and at least one field detecting element for detecting an electric field on the straight line. The m electric charges are a quadrupole, planar hexapole, planar octopole, solid octopole, etc. In order to construct a quadrupole, four electrodes (11 to 14) are arranged on the corners of a square, and a detector electrode (20) is disposed at the center of these electrodes (11 to 14). A vein sensor, etc. are constructed using this detector.
(FR) L'invention porte sur un détecteur et sur un procédé de détection capables de détecter divers objets tels que des vaisseaux sanguins avec une sensibilité élevée et une précision élevée sur la base d'un nouveau principe. Le détecteur consiste en m (m est un nombre pair égal ou supérieur à 4) électrodes destinées à générer m charges électriques à symétrie de rotation selon au moins une ligne droite, la somme des valeurs de charge de ces charges électriques étant presque nulle, et au moins un élément de détection de champ destiné à détecter un champ électrique sur la ligne droite. Les m charges électriques sont un quadripôle, un hexapôle plan, un octopôle plan, un octopôle solide, etc. Afin de construire un quadripôle, on dispose quatre électrodes (11 à 14) aux coins d'un carré, et on dispose une électrode de détecteur (20) au centre de ces électrodes (11 à 14). On réalise un détecteur de veine, etc., à l'aide de ce détecteur.
(JA) 新規な原理に基づき、血管などの各種の対象物を高感度かつ高精度で検出することができる検出装置および検出方法を提供する。少なくとも1つの直線の周りに回転対称なm個(mは4以上の偶数)の電荷であってそれらの電荷量の合計が略0であるものを発生させるm個の電極と、上記の直線上の電界を検出する少なくとも1つの電界検出素子とにより検出装置を構成する。m個の電荷は4重極、平面6重極、平面8重極、立体8重極などである。4重極を構成する場合には正方形の頂点に4個の電極(11~14)を配置する。これらの電極(11~14)の中心に検出電極(20)を配置する。この検出装置を用いて静脈センシング装置などを構成する。
