APPARATUS FOR DETERMINING THE QUALITIES OF AN IRRADIATABLE BODY BY MEANS OF PENETRATING RADIATION

摘要

The invention relates to an apparatus for determining the qualities of irradiatable bodies, for instance pieces of meat, comprising radiating means for determining the qualities of the irradiatable bodies only by means of radiation. In preference the radiating means comprise: a device for parallel irradiation from one side of an at least partly irradiatable body; a device for receiving the radiation leaving the irradiatable body and deriving a transmission signal therefrom; means for deriving from the transmission signal information concerning the qualities of the irradiated body. According to a preferred embodiment the apparatus comprises height measuring means for determining the dimensions of the irradiatable body in the direction substantially parallel to the radiation direction over at least a part of the surface of the irradiatable body transversely of the radiation direction, and for deriving therefrom a height signal. According to another preferred embodiment the apparatus comprises reflection determining means for determining the local reflection coefficient of at least a part of a surface of the irradiatable body and for deriving therefrom a reflection signal.
