Photonic crystal sensing applications have been widely used in numerous domains. In this work, we present a comprehensive framework that leverages photonic crystal sensing through advanced image processing and machine learning techniques. Unlike many previous works, which only utilize color and spectrum information for photonic crystal sensing, this research aims to classify photonic crystal morphologies based on their pattern changes in the RGB camera image domain alone. By utilizing computer vision and machine learning methods for pattern extraction, topological analysis, dimensionality reduction, and neural feature analysis, our findings demonstrate that the observed patterns in photonic crystal sensing indeed correlate with chemical imprinting.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
