  • Page 4: Introduction

    Harvesting immature fruit has a high impact on fruit eating quality. Judging fruit maturity by shape and color alone results in varying success. The F-750 solves this issue with its simple user interface and precise measurements. It comes equipped with GPS for spatial mapping, enabling users to generate orchard-wide maps of fruit parameters, such as planning for harvest sequences and improving crop management techniques.

    Partial Least Squares (PLS): mathematical method used by the F-750 to generate a mathematical model of regression coefficients. PLS1 only predicts a single trait with a single regression vector. PLS2 can be used to predict multiple traits with a single regression vector. The F-750 will do PLS1 multiple times to predict multiple traits.
  • Page 20 F-750 Instruction Manual rev. 3/26/2014 regression vector specific to a single property (such as dry matter). By taking the dot product of the regression vector and a scan of an unknown sample, a concentration can be determined. These are stored in a single row wise vector, there is 1 element in the vector for every pixel used the regression.
