Title (EN) OPTICAL READERS
(FR) LECTEURS OPTIQUES
Abstract:
(EN) Optical readers are disclosed in examples herein. An example optical reader including a light source to emit a light beam; and a spot pattern generator to receive the light beam and to generate a two-dimensional spot array from the light beam, the two-dimensional spot array to be directed toward a substrate having nanostructures, the two-dimensional spot array to be sensed to detect a presence or an absence of a substance of interest on the substrate.
(FR) La présente invention concerne, selon des exemples, des lecteurs optiques. Un lecteur optique exemplaire de la présente invention comprend une source lumineuse destinée à émettre un faisceau lumineux ; et un générateur de motif de point destiné à recevoir le faisceau lumineux et à générer un réseau de points bidimensionnel à partir du faisceau lumineux, le réseau de points bidimensionnel étant dirigé vers un substrat doté de nanostructures et le réseau de points bidimensionnel devant être détecté afin de détecter la présence ou l'absence d'une substance d'intérêt sur le substrat.
