PORTABLE APPARATUS FOR THE NON-DESTRUCTIVE MEASUREMENT OF THE INTERNAL QUALITY OF VEGETABLE PRODUCTS

摘要

Instrument for measuring the properties of vegetable products, comprising: - an energy source adapted to direct a radiation against the fruit, - means for picking up the radiation being re-emitted by said fruit, - a spectrograph analysing said radiation, - means for conveying said radiation into the spectrograph, - means for processing the data generated by the spectrograph, in which the energy source comprises a plurality of LEDs contained in a single portable casing provided with a handgrip (1) and a probing head (2). The spectrograph and the processing means (15) are physically separated from said portable casing, to which they are electrically and optically connected via at least a multiple optical /electric connection (8). The LEDs are provided in closed-loop arrangements on the surface of the probing head and said means for picking up the re-emitted radiation are arranged at the centre of the rings formed by the LEDs that emit radiations whose respective emission spectra are contiguous.
