This paper describes the spectral image measurement of the agricultural products based on the near infrared diffuse reflectance. Spectral image was obtained by a developed measuring system using the model samples and the real lettuce samples. The correlation among of the near infrared images and the chemical or the taste preferences has been studied. This image measurement could offer a new image information server to monitor the growth of the agricultural products on the fields. This paper also describes the maturity judgments model based on spectral image information.
