Abstract
The invention relates to an analysis device for the automatic grading of products, in particular of fruits or vegetables, comprising punctiform lighting means (4, 8, 12) capable of generating a polarised incident beam, means (19) for deflecting the polarised incident beam which are capable of forming a crosswise line of light, lateral reflection means (22, 23) capable of allowing the products to be lighted laterally, lower reflection means (28, 29) capable of allowing the lower face of the products to be lighted, and separation means (6, 10, 14) aligned on the optical axis of the polarised incident beam and suited to separating said incident beam and the backscattered depolarised light energy.
