Hyperspectral Reflectance and Fluorescence for Assessing Apple Quality

2005 Tampa, FL July 17-20, 2005, 2005
Fluorescence and hyperspectral reflectance scattering have recently been researched for measuring fruit post-harvest quality and condition and they are promising for nondestructive detection of fruit quality. The objective of this research was to use hyperspectral reflectance and fluorescence for measuring apple fruit quality.

Measurement and analysis of reflectivity accuracy of hyperspectral reflectometer

Fifth International Symposium on Laser Interaction with Matter, 2019
The principle of self-developed hyperspectral reflectometer is introduced. The instrument has long-term automatic observation capability, and its spectral range covers the visible-short-wave infrared band. The functions of instrument include ground spectral reflectance observation, sky diffuse irradiance, total irradiance, diffuse total ratio ...

Early detection of decay on apples using hyperspectral reflectance imaging combining both principal component analysis and improved watershed segmentation method

Postharvest Biology and Technology, 2019
In addition to other surface quality attributes such as size, color and shape, during sorting of harvested apple fruit, early detection of decay is important due to its infectiousness and potential food safety issue.

FEM explicit dynamics simulation and NIR hyperspectral reflectance imaging for determination of impact bruises of Lycium barbarum L.

Postharvest Biology and Technology, 2019
A 3D scanner was used to reverse engineer a model to assess impact bruising of fresh Goji (Lycium barbarum L.) fruit. Based on the results of physical compression tests, an elastic-plastic model was selected as the material mechanics model for the fruit.
