Note 1 to entry: Reflections that undergo scattering are called diffuse ref
32、 lections. Diffuse ref lections are measured by means of an integration sphere, while properly averaging over all angles of illumination and observation. 3.3 optical resolution ability of the storage material to resolve physical details by optical means Note 1 to entry: The (spatial) resolution is t
33、ypically expressed in line pairs per millimetre. 3.4 diffraction effect occurring when light is incident on an optical structure, the light is diffracted in discrete directions, called diffraction orders 3.5 diffraction efficiency relation of the power of the diffracted light beam, P diff , to the i
34、ncident power of the readout beam, P inc : P P Note 1 to entry: The diffraction efficiency is dependent upon the holographic storage medium. It varies between 1 % and 100 %. 3.6 diffraction grating device having periodic variations of reflectivity and/or refractive index and/or optical path length 3

36、ed upon the use of an authentication element integral to the optical medium; see the existing standards ISO/IEC 11694-3 and ISO/IEC 11695-3. 5 Physical characteristics of authentication elements 5.1 Dimensions The dimension of the authentication element is user defined in compliance with accessible
37、optical area as specified in ISO/IEC 11693-2. A minimum area of a b, whereas a = 10 mm and b = 10mm is recommended. 5.2 Technology combinations Numerous combinations of technology are possible; see ISO/IEC 11693-2.2 ISO/IEC 2015 All rights reservedBS ISO/IEC 11693-3:2015ISO/IEC 11693-3:2015(E) 5.3 C
38、ard construction ISO/IEC 7810 applies. 5.4 Cross section at accessible optical area See Figure 1. The accessible optical area contains an area that is reserved for the authentication element. The authentication element is composed of different layers: which can include an adhesive layer, a substrate
39、 layer, a reflective layer, a storage layer and one or more protective layers to protect the sub- layers from damage e.g. by surface damage, humidity and other environmental influence. In the simplest configuration only a storage layer is required. NOTE Drawing not to scale. Figure 1 Cross-section o
40、f the authentication element for optical memory cards Authentication elements are laminated, coated, or glued onto the card surface or inserted into the card body. 5.4.1 Protective layer(s) There is one or multiple protective layer(s) to protect the sub-layers (storage layer, reflective layer) from
41、surface damage, humidity and other environmental influence. The protective layer shall be transparent to the writing and reading beam. When using a reading or writing beam with linear or circular polarization, the protective layer shall be free of birefringence. The protective layer ensures that the
42、 authentication element can survive the action of a destructive influence to the extent that it continues to show optical characteristics which conform to the base standard. 5.4.2 Storage layer The storage layer is a photosensitive material applied to the reflective or substrate layers. Examples of
43、materials, which can be used are: high-resolution photographic silver-halide film; silver-halide sensitized gelatin; dichromated gelatin; photoresists; photopolymers; functionalized liquid crystalline polymers; metal films; ISO/IEC 2015 All rights reserved 3BS ISO/IEC 11693-3:2015ISO/IEC 11693-3:201
44、5(E) dye-polymer films. The thickness of the storage layer may vary depending on the specific optical characteristics of the material chosen. The material as well as the parameters for recording and/or reading authentication elements shall be specified by the card manufacturer. The material composin
45、g the storage layer determines the parameters for recording and reading information (wavelength of writing/reading beam, writing/reading power). Information can be macroscopic, microscopic or holographic; a single authentication element shall incorporate information in one or more of these forms. 5.
46、4.3 Reflective layer A reflective layer is necessary if the storage layer is not inherently reflective. The reflective layer can be metallic or non-metallic: metals which can be used include aluminium, silver, tin, gold, titanium and chromium. Non metallic materials which can be used include materia
47、ls with a very high refractive index such as special polymer films. The thickness of the reflective layer may vary depending on the specific optical characteristics of the selected material. 5.4.4 Substrate layer A substrate layer is necessary if an authentication element is attached to the card bod
48、y, unless the card body itself serves as the substrate layer. The substrate layer shall be made of a material which provides a flat, smooth surface on the side to which the optical storage layer is applied and with a material which can be bonded to the card surface on the other side. The thickness o
49、f the substrate layer may vary depending on the materials used and the manufacturing process employed. 5.4.5 Adhesive layer An adhesive layer is necessary if the substrate layer or storage layer of the authentication element is not self adhering to the card surface. 5.5 Bending stiffness ISO/IEC 7810 applies. 5.6 Card warpage ISO/IEC 7810 applie
