Abstract

Electro-optical system for classifying fruit and vegetables. The object of this Patent is an electro-optical system for classifying fruit and vegetables, which has a single lens (1) common to two cameras, one colour (RGB) (3) and the other infrared (IR) (5). Behind the lens is a half mirror (2) with a filter (6), which the object line/fruit hits at an angle of 45 degrees, reflecting in the infrared spectrum and leaving the captured image in the colour camera (RGB) (3). The deviated spectrum is newly reflected in a mirror (4) parallel to the former with its filter (7), reaching the infrared camera (IR) (5).<IMAGE>
