The fabrication of a stable, reproducible optical imaging phantom is critical to the assessment and optimization of optical imaging systems. In this study, we present a novel design of optical phantom based on metal-doped glass-ceramics. The matrix was doped with nickel ions to imitate the absorption of haemoglobin, and scattering levels representative of tissue were induced through controlled crystallisation in the glass-based phantom at elevated temperature. Our glass-based optical phantom can provide controlled levels of optical scattering and absorption to mimic the optical properties of human tissues with excellent optical homogeneity, and potentially long-term stability and reproducibility.
