A system and a method for inspecting a stream of products (&#x2033;) is disclosed, comprising a scanning focused light beam () for scanning the product stream and a camera () for detecting light beams directly returned from the scanned product stream, whereby the scanning movement of the focused light beam is synchronized with the exposure time of the camera.

System and method for individually inspecting objects in a stream of products and a sorting apparatus comprising such system

The invention concerns a method and apparatus for sorting a stream of products by scanning this stream of products with a bundle of concentrated light and analyzing the light originating from the scanned products and a background element, wherein this background element is chosen such that the corresponding detected light signal differs from the light signals originating from the products to be sorted in at least one parameter and wherein one or more control signals are generated by shifting the background level of the observed light signals to a signal level chosen such that, in the thus obtained signal, the signal level of the signal of a scanned product to be accepted distinguishes itself from the signal level of the signal of a scanned product to be rejected.

Method and device for sorting products

Disclosed is a method and system for inspecting and sorting unsuitable or irregular objects in a stream of products, the system includes means for scanning the stream of products along a scan line. The scan line is formed by means of at least one light source directing light along the scan line, and means for detecting light beams reemitted by the product stream upon scanning. The scanning means includes a focusing means for concentrating the light in at least one dimension. The detecting means includes a focusing means for forming an image in an image plane. The detecting means is oriented towards the scan line such that points on the scan line form a projected scan line in the image plane and the image substantially located in the image plane is substantially focused in at least one dimension by the focusing means. The detecting means also includes a spatial filtering means that filters the image in substantially the direction perpendicular to the direction of the projected scan line.
