Patent abstract
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.
