Detecting shape defects in ferrite cores
نویسندگان
چکیده
In the framework of a European technological research project 2], a general method is presented for shape measurement and defect detection of industrially produced objects using the characteristic 2D projections of the objects. The method is applied to the visual inspection and dimensional measurement of ferrite cores. An optical shape gauge system is described, based on rotation-invariant shape matching. A novel shape representation is introduced that facilitates the invariant matching. Special attention is paid to nding the optimal reference position and orientation (pose) of the measured shape for invariant comparison to the reference shape. This problem arises because shape defects may deteriorate any of the dimensions.

متن کاملCONSTRUCTION AND USE of BROADBAND TRANSFORMERS
Broadband transformers are not difficult to understand. They are commonplace in today's amateur technology. Most broadband transformers are wound on ferrite toroids or rods. Some are wound on powdered-iron cores, while others are formed on pot or cup cores. We will confine our discussion to transformers that are wound on ferrite toroids or balun cores (sometimes called "binocular" cores. Basic ...
