Embodiment Construction

[0025] Holograms can be formed into non-planar mirrors in a number of ways. It will be appreciated that the different techniques described herein can be used alone or in combination to achieve results.

[0026] A preferred embodiment of the invention involves recording holograms using non-planar mirrors. The type of mirror chosen depends on the desired effect on the incident light of the resulting hologram. Many different types of non-planar mirrors are known, such as concave and convex mirrors (eg semi-cylindrical mirrors), reflective beads, and the like. Alternatively the mirror may be a prism such as a corner cube prism, a right angled prism, a Porro prism, an Amici prism, a Dove prism, a pentaprism, a rhomboid prism or a Lernan-Springer prism

[0027] In a preferred embodiment the mirror is a concave mirror. This allows the fabrication of sensors that have a focusing effect on incoming light. The sensor has a wide range of potential uses, for example as a small subcuta...

Abstract

The invention relates to a holographic sensor, a combination device, a subdermal implant and correlation methods. The sensor (8) comprises a medium and a hologram disposed throughout the volume of the medium, wherein an optical characteristic of the hologram changes as a result of a variation of a physical property of the medium, and wherein the hologram is formed as a non-planar mirror.

Description

[0001] This application is a divisional application of the invention patent application with the name "holographic sensor" and application number 200480024257.5 submitted on July 21, 2004. technical field [0002] The present invention relates to holographic sensors. Background technique [0003] WO-A-95 / 26499 discloses a holographic sensor. The sensor includes a holographic support medium and a hologram located throughout the medium. The supporting medium interacts with the analyte, causing changes in the physical properties of the medium. The change causes a change in the optical characteristics of the holographic element, such as deflectability, reflectivity, refractive index or absorbance. When replaying the hologram (eg, using incident broad-wave, non-ionizing electromagnetic radiation), any changes, if any, are observed using optical detectors, such as color changes. Optical detectors can be spectrometers or just the naked eye. [0004] Another method of manufactur...
