Abstract

In un dispositivo di rivelazione di posizione sfalsata del tipo in cui una luce illumina la superficie terminale di una rocca ed un filo in posizione sfalsata viene rivelato fotografando la superficie terminale mediante una camera di ripresa CCD, un dispositivo di rivelazione di posizione sfalsata ha un codificatore binario che converte ciascun pixel dei dati di immagine in un dato in codice binario, un dispositivo di memorizzazione, per memorizzare i dati di pixel in codice binario ed un circuito di rivelazione che rivela ciascun pixel (1) o (0) in ciascuna scansione.
