Abstract: An inspection apparatus for internally inspecting tubular members has a body having an inspection window. Located inside the body is a camera, a laser and associated reflectives, one of the reflectives being rotatable by a motor such that a beam of light is directed through the window to illuminate an axial extending strip of the entire 360.degree. interior circumference of the tubular member. Light is reflected from the window and the tubular member to be focussed onto the camera lens. The images reflected by the window and the tubular member interior surface are correlated so that, for example, ovality of the tubular member may be detected. The data may also be compared with data stored in a computer.
