| Abstract(in English) | In this work, we examined the possibility of real time multispectral imaging to measure water concentration in a liquid mixture of water and ethanol using a set of wavelength filters made of autocloning-type photonic crystals (PhCs) and an InGaAs near-infrared (NIR) camera. In the first half, the absorption spectrum of a liquid mixture with various component ratios and the basic techniques of filter design are presented. In the second half, a design scheme of PhC filters (PhCFs) for the specific measurement of water content in the liquid mixture is described. Also, the filter's numerical design, its fabrication and transmission characteristic are examined. Afterwards, a preliminary result of the imaging experiment for a mixture of water and ethanol is presented. |
