| description | The invention relates to a fruit reheological parameter detection method and system. The method comprises the following steps: firstly, detecting characteristic parameter information of a fruit; secondly, exciting earthquake waves on the surface of the fruit through pulse laser; finally according to the pulse laser frequency and the characteristic parameter information of the fruit, acquiring a surface wave speed of the earthquake waves, the S-wave speed of the earthquake waves, and the P-wave speed of the earthquake waves, and furthermore acquiring reheological parameter of the fruit, whereinthe reheological parameters of the fruit comprise at least one of an elastic modus, a Poisson system and hardness indexes. By adopting the method, the surface of the fruit is acted by the pulse laser, the surface layer of the fruit is not damaged, meanwhile surface waves, S waves and P waves can be excited, relatively comprehensive quality information can be carried by the waves, and thus the reheological parameters of t |
