Apparatus for the inspection of cylindrical objects having a borescope device |
摘要 |
Apparatus for the inspection of the end surface of a cylindrical object including a device for irradiating the end surface of the object, a detector for detecting radiation reflected by the end surface substantially parallel to the axis of the object and a calculator for calculating the proportion of the end surface which has reflected radiation directly to the detector device, wherein the means for irradiating comprises a ring source the center of the ring being substantially co-incident with the axis of the object and being substantially transparent to reflected radiation so that light reflected to the detector passes unhindered through the ring, the ring source having associated therewith a device permitting substantially uniform irradiation across the said end surface.
