CA 2579290
The invention relates to a sensor comprising a medium and, disposed therein, a hologram, wherein an optical characteristic of the medium changes as a result of a variation in a physical property of the medium, wherein the fringes of the hologram are formed by silver grains and wherein the medium comprises a material which does not bind silver. The brightness and sensitivity of such holographic sensors is increased as a result of reduction in the levels of unwanted (~background~) silver binding.
L'invention concerne un détecteur comprenant un support, et un hologramme disposé à l'intérieur de celui-ci, dans lequel une caractéristique optique du support est modifiée en raison d'une variation d'une propriété physique du support, les franges de l'hologramme étant formées par des grains d'argent. Le support comprend un matériau qui ne se fixe pas à l'argent. La clarté et la sensibilité desdits détecteurs holographiques sont améliorées en raison de la réduction des niveaux de liaison de l'argent non souhaitée (<= arrière plan >=).
