ABSTRACT:
A method and apparatus for non-destructive internal and external inspection of produce, including the detection of pits in various stone fruits. The apparatus transmits a first plurality of beams of light (20) across inspection zone (14) and transmits a second plurality of beams of light (30) across inspection zone (14) in a direction transverse to beams of light (20), thus forming an X-Y plane. As article of produce (10) passes through inspection zone (14) along the Z-axis, a first plurality of sensors (24) and a second plurality of sensors (34) detect the variations in the intensity of the beams of light and the data is processed to produce a three-dimensional "picture" of the article of produce. Size, symmetry, external defects, and internal structure are determined as a result of processing the data collected. The apparatus and method can be used for detecting pits or surface defects, and for sorting or rejecting articles of produce based on size, symmetry, external defects or internal structure.
