Abstract
In this paper, we describe a device used to measure the distance betwe en an eddy-current proximity sensor and a metallic surface in front of it. The goal is to restore the profile of the metallic surface. We pr esent the different steps of this realization and the development of a deconvolution algorithm. The deconvolution algorithm allows us to obt ain a model of the device. It is also used to invert this model, there fore allowing the restoration of the input signals corresponding to th e degraded image of the profile of the metallic surface.
