Abstract
Inner profile measurement has a lot of request for the applications in field of mechanical industry and even in the medical and dental fields. We proposed measurement method of inner diameters of pipes and/or holes using a ring beam device which consists of a conical mirror and a laser diode. This measurement method is based on optical sectioning of inner wall. This optically sectioned profile is analyzed to calculate the inner diameter and/or profile. Here, an optical instrument with a simple and compact configuration is reported for the inner profile measurement. As experimental results, we show performance of the instrument and some examples for inspection of mechanical components.
