A high speed non-contact beam scanning device (20) sized and shaped to provide the ergonomic benefits of a pen or wand (1). The device is well suited for reading one or two dimensional bar-code (9, 10) or other printed matter. In order to achieve the high density optical packaging necessary for its high performance to size benefits, the device employs a novel in-line or "axial" gyrating, or "axial" scan element. Reflected light which carries information contained on the target, is collected by an internal non-imaging light concentrator (34) and is processed by signal processing electronics (24). Communication from the device is achievable by a cable or by wireless communication technique.

L'invention concerne un dispositif (20) de balayage par un faisceau, sans contact, et ultra-rapide, dont la forme et les dimensions présentent les avantages ergonomiques d'un crayon-lecteur ou d'un lecteur manuel (1). Le dispositif est adapté pour lire un ou deux code(s) à barres dimensionnel(s) (9, 10) ou tout autre motif imprimé. Afin d'obtenir la haute densité de composants optiques permettant d'assurer la haute performance du dispositif avec les avantages de sa taille, ce dernier utilise un nouvel élément de balayage "axial" ou "axial" giratoire direct. La lumière réfléchie, qui transporte les informations placées sur la cible, est collectée par un concentrateur (34) de lumière interne non imageur et est traitée par un système électronique (24) de traitement de signaux. La communication est effectuée à partir du dispositif par un câble ou par une technique de communication sans fil.
