The pitch of machine parts influences its quality and therefore the quality control of pitch by precise measurement is demanded strongly in industries. The measurement of pitch is, however, usually time-consuming process if touch probe is used. Noncontact measurement is ideal but it has difficulty in working distance or stability of measurement. In this report, a new noncontact measuring method of pitch is proposed. The image of surface of moving object is taken consecutively and the degree of focusing is evaluated for each image. The pitch is measured by analyzing the whole wave form corresponding to the change of focusing value. The principle of measurement is proposed and the influence of measurement conditions is investigated.
