Claims7
A sensor comprising a medium and, disposed throughout the volume thereof;
- a holographic element whose fringes are defined by different degrees of swellability in a liquid.
A method for the production of a sensor comprising a medium and, disposed throughout the volume thereof;
- a holographic element whose fringes are defined by different degrees of swellability in a liquid, wherein said method comprises the recording of a holographic image by selective (de)polymerisation of the medium, wherein the medium is in a swellable state during the recording.
