A Study on Fiber Sensing Technique Used for Fruit Interior Quality Inspection

Fiber sensing technique has been widely applied in spectroscopic analysis. The objective of this research was to investigate a fiber sensing technique in reflectance, interactance and transmittance mode for rapid acquisition of spectral information to predict the interior quality of fruit. A NIR sensing system with a specially designed probe assembly was designed for fruit interior quality inspection and the measurement principle was disscussed. Three measurement modes including reflectance, interactance and transmittance were analyzed by different fruit experiments. It was concluded that the best measurement mode used to predict the fruit interior quality is interactance mode. The research evolutions of fiber sensing technique were reviewed and the following studies were also suggested.
