| Outline of Research at the Start |
卵殻の紫外から近赤外までの透過，反射，蛍光の分光情報を蓄積することにより，鶏卵中の品質，鮮度，鶏胚の非破壊モニタリングを行う。また，卵殻の厚さを非破壊計測可能な波長帯の探索，その消費速度の雌雄による違いを計測する。続いて鶏胚のバイタルサインのモニタリング可能なシステムを構築する。本実験成果により，孵化前の雌雄判定および孵化中の鶏胚の計測に貢献する。

| Outline of Annual Research Achievements |
We conducted several experiments during this fiscal year, April 2021 to October 2021. Some of the experiments were new (eggshell and incubation studies) and some for repeatability on optical properties of eggshell in Terahertz Region (0.5-2.0 THz) to interpret biological phenomena of chicken eggshell and dependence of mother bird age and breed. We also took eggshell ultra-structure using electronic microscopic image. We obtained several fundamental findings which was presented in Japan Society of Agricultural Machinery and Food Engineers (JSAM) 79th annual scientific conference in 2021. We found clear and significant difference of eggshell optical properties like refractive index of incubated and non-incubated eggshell, difference between eggs from older parent flock and eggs from younger flock. The refractive index in terahertz region indicates the density of eggshell. Based on the above observation, it was possible to develop a deep learning based non-destructive protocol on mother birds tracing system for their health status monitoring based on eggshell optical properties and micro-structure.
