Based on the principle of photonic crystal structure color, a one-dimensional Fibonacci quasi-crystal structure colorimetric sensor is designed and optimized. The optical model of quasi-crystal structure was constructed by iterative method with the number of iterations being 5. Quasicrystal structure consists of alternating arrangement of chitin and ethanol. A structure with higher color sensitivity was designed by changing the chitin filling ratio in the quasicrystal structure. Based on this structure, a high-sensitivity colorimetric sensor was designed by changing the amount of ethanol volatilization to monitor the change of reflectance spectrum.
