Abstract:
1. Apparatus for non-destructive measurement of internal properties of individual vegetable or fruit products, comprising: LEDs constructed and arranged to emit radiation into a vegetable or fruit product; pick-up structure constructed and arranged to pick up radiation, emitted by said LEDs, that has entered the vegetable or fruit product and then exited the vegetable or fruit product; a hollow cylinder between said LEDs and said pick-up structure for preventing radiation emitted by said LEDs from directly reaching said pick-up structure; a terminal ring adapted to be brought into abutment with the vegetable or fruit product; a spectrometer; structure for conveying to said spectrometer the radiation picked up by said pick-up structure; and structure for processing a spectrum frequency and amplitude data as produced by said spectrometer upon the radiation picked up by said pick-up structure being analyzed by said spectrometer, wherein said LEDs are contained in a portable casing including a handgrip and a probing head constructed and arranged to be brought into close proximity of, or into contact with, the vegetable or fruit product, wherein said spectrometer and said structure for processing are physically separated from said portable casing, and are electrically connected to said portable casing via an electrical conductor, and wherein said hollow cylinder projects from said probing head beyond terminal borders of said LEDs and said pick-up structure.
