Application of Two-Diode Autodynes in Devices for Radiowave Control of Product Dimensions

Resumo

We describe the operating principle of a two-diode autodyne and the basic methods of non-contact determination of product size. We consider the application features of two-diode autodynes in determining the sizes of products by the Doppler method, as well as a phase method for determining small deviations of the controlled product from a reference sample.
