Abstract
The present invention relates to a scanning device for determining at least partial cross-sectional profiles of food products to be sliced in accordance with the light cutting process, having at least one illumination device for generating a light line on the surface of a product and having at least one detection device for taking images of the product surface including the light line, wherein the illumination device includes at least one light source which is configured to generate a light beam propagating in the direction of a scanning region for the product in a scanning plane and widening in so doing and includes an optically effective device which is arranged in the propagation path of the widening light beam and which is configured to counter the divergence of at least some of the incident light.
Claims21
A scanning device for determining at least partial cross-sectional profiles of food products to be sliced in accordance with the light cutting process, comprising:
- at least one illumination device for generating a light line on the surface of a product;
- and
- at least one detection device for taking images of the product surface including the light line;
- wherein the illumination device includes at least one light source which is configured to generate a light beam propagating in the direction of a scanning region for the product in a scanning plane and widening in so doing, and an optically effective device which is arranged in the propagation path of the widening light beam and which is configured to counter the divergence of at least some of the incident light,
- wherein the optically effective device includes at least one Fresnel lens, and
- wherein the extent of the optically effective device is larger in the scanning plane than the corresponding extent provided as a maximum for a product to be scanned in the scanning region.
An apparatus for slicing food products, in particular a high-performance slicer, comprising:
- a product feed which is configured to feed at least one product to be sliced to a cutting plane S in which at least one cutting blade moves, in particular in at least one of a rotating and an orbiting manner;
- and at least one scanning device for determining at least partial cross-sectional profiles of food products to be sliced in accordance with the light cutting process, the scanning device comprising at least one illumination device for generating a light line on the surface of a product and at least one detection device for taking images of the product surface including the light line, wherein the illumination device includes at least one light source which is configured to generate a light beam propagating in the direction of a scanning region for the product in a scanning plane and widening in so doing, and an optically effective device including at least one Fresnel lens which is arranged in the propagation path of the widening light beam and which is configured to counter the divergence of at least some of the incident light wherein the extent of the optically effective device is larger in the scanning plane than the corresponding extent provided as a maximum for a product to be scanned in the scanning region.
