ABSTRACT:
An elastomeric distance gage is formed of a ring of elastomeric film to which is joined a vee-shaped ear of elastomeric film. The ring of this gage fits removably onto a video head or other imager at the distal tip of a borescope. The legs of the nose portion converge to a distal tip which is within the viewing field of the borescope imager. To determine the size of an object, the gage is brought into contact with the object. The gage nose will deflect and this is visible in the viewing screen of the borescope. The object can be measured by comparison to a known width of the flat apex of the gage. Also, at this contact point, the object is a predetermined known distance from the borescope tip, and the size of the object can be determined by counting the number of pixels in the displayed image from one edge of the object to an opposite edge.
