Abstract: An optical device for forming a distribution of a three-dimensional light field comprises: an array of individually addressable unit cells; each unit cell in the array of unit cells comprising a stack including: at least one electrode; and a resonance defining layer, comprising at least a phase change material, PCM, layer, wherein the resonance defining layer is patterned to define a geometric structure dimensioned for defining a wavelength-dependent in-plane resonance of an electromagnetic wave; wherein the at least one electrode causes a phase change of the phase change material based on receiving a control signal to alter a wavelength-dependency of resonance in the resonance defining layer for controlling the optical property of the unit cell; wherein unit cells in the array of unit cells are separated such that the PCM layer of a unit cell is separated from the PCM layer in an adjacent unit cell.

Abstract: A method for measuring a concentration of a biogenic substance in a living body includes steps of: preparing an apparatus including a light source, a substrate which has periodic metal structures and generates surface enhanced Raman scattering light by being irradiated with light from the light source, and spectroscopic means which disperses and detects the light, wherein the periodic metal structure is arranged with first and second distances in first and second direction respectively, the first distance is set to generate surface plasmon by matching a phase of the light from the light source, and the second distance is smaller than the first distance and is set between 300 nm and 350 nm; irradiating the substrate with the light from the light source to generate the surface enhanced Raman scattering; detecting the scattering with the spectroscopic means; and calculating the concentration of the biogenic substance based on the scattering.
