Abstract: A structural color changeable material includes a strain body and surface plasmon generating particles. In the strain body, a strain is produced by an external pressure or an internal change. The surface plasmon generating particles generate surface plasmon and are contained in the strain body. The surface plasmon is generated by an incident light with a wavelength of 2400 nm or less. A mean particle size of the surface plasmon generating particles is equal to or less than the wavelength of the incident light. The surface plasmon generating particles are periodically arranged parallel to an in-plane direction of a reflection surface of the incident light.

The elastic elements (22) are arranged periodically, The arrangement of the elastic elements (22) is illuminated using light, the coherence length of which is larger than the average spacing of adjacent elastic elements (22). A diffraction image is hereby created of the illuminating light scattered on the arrangement of elastic elements (22), and at least a portion of the diffraction image is detected by an optical sensor (32) directly or after interaction with further optical components. The detected image or image signal is subsequently analyzed in order to determine information relating to the deflection state of the elastic elements (22) therefrom.
