The AEYEOT team is composed of cross-disciplinary professionals in optical system design, AI algorithms, and cloud big data, and has collaborated with the Food Industry Research and Development Institute, major textile manufacturers, and major food manufacturers to develop spectral analysis technology. We develop real-time analysis solutions for manufacturing processes that require rapid quantification of ingredients; we also provide real-time identification solutions for manufacturing processes that require rapid and precise differentiation of delicate colors. These solutions have undergone field verification in food factories and textile factories, enabling production line operators to obtain real-time results and make real-time adjustments, thereby significantly improving inspection quality. Spectroscopy transcends the limits of the human eye; from delicate surface colors on the outside to quantified ingredient ratios deep within, the footprints of light tracking are everywhere, and the light passes without leaving a trace. We aspire to make quality management even simpler and leaner.
