| Abstract: | The principle of electro-optical on-line size measuring system and the way to reach it by using optic-fibre searching unit instead of optical lens has been described in this paper. The practical applied circuit and the treatment method of singnal is discussed in detail. The adoption of differentiation in signal treatment highten the precision on edge resolving and the employment of microprocessor on compute and display raise the measuring precision of system and realize automatic measruemeat so that this is a high preaision dynamic size measuring system. |
