Title (EN) COATINGS FOR INCREASING NEAR-INFRARED DETECTION DISTANCES
(FR) REVÊTEMENTS D'AUGMENTATION DES DISTANCES DE DÉTECTION PROCHE INFRAROUGE
Abstract:
(EN) A method for increasing a detection distance of a surface of an object illuminated by near-IR electromagnetic radiation, including: (a) directing near-IR electromagnetic radiation from a near-IR electromagnetic radiation source towards an object at least partially coated with a near-IR reflective coating that increases a near-IR electromagnetic radiation detection distance by at least 15% as measured at a wavelength in a near-IR range as compared to the same object coated with a color matched coating which absorbs more of the same near-IR radiation, where the color matched coating has a ΔΕ color matched value of 1.5 or less when compared to the near-IR reflective coating; and (b) detecting reflected near-IR electromagnetic radiation reflected from the near-IR reflective coating. A system for detecting proximity of vehicles is also disclosed.
(FR) L'invention concerne un procédé d'augmentation d'une distance de détection d'une surface d'un objet éclairé par un rayonnement électromagnétique proche infrarouge consistant : (a) à diriger un rayonnement électromagnétique proche infrarouge depuis une source de rayonnement électromagnétique proche IR vers un objet au moins partiellement revêtu d'un revêtement réfléchissant proche IR qui augmente une distance de détection de rayonnement électromagnétique proche IR d'au moins 15 % telle que mesurée à une longueur d'onde dans une plage proche IR par comparaison avec le même objet revêtu d'un revêtement à correspondance de couleur qui absorbe davantage le même rayonnement proche infrarouge, le revêtement à correspondance de couleur présentant une valeur de correspondance de couleur ΔΕ de 1,5 ou moins par rapport au revêtement réfléchissant proche IR ; et (b) à détecter un rayonnement électromagnétique proche infrarouge réfléchi réfléchi par le revêtement réfléchissant proche IR. L'invention concerne également un système de détection de proximité de véhicules.
