Chinese Abstract

為解決當前近紅外光譜分析技術應用於農産品品質分析時所出現的預測模型不穩定、適應性不好、預測精度難於進一步提高等問題,我們認為,研究組織內部的光學性質及其光傳輸規律是其關鍵。為此,我們首先要對農産品生物組織的光學參數進行檢測研究。本文通過對生物組織光學參數目前用的一些測量方法進行了分析研究,其中著重介紹了基於空間分辨技術、時間分辨技術和積分球技術的光學參數測量方法,並對這些方法的優缺點做了比較,為選擇一種適用於農品生物組織光學參數的測量方法提供了依據。

English Abstract

At present, near infrared spectroscopy technology is widely applied to quantitative analysis of agricultural products, but a lot of problems are in the way, for instance, the calculation model is not stable and suitable enough for predicted samples, the prediction precision is difficult to be improved more. To resolve these problems, we have to study the optical properties and light propagation in tissue, and the optical properties measurement methods are studied firstly. In this paper, a few optical properties measurement methods used today are presented and investigated; especially, the measurement methods based on spatially-resolved spectroscopy, time-resolved spectroscopy, and integrating-sphere system are described in detail. Accordingly, the advantages and disadvantages of these measurement methods are compared to select a suitable measurement method to determine the optical properties of agricultural products tissue.
