In detection of a defect in a part of an object having a surface which is substantially a surface of revolution, the surface of the inspected part is illuminated by light rays which are emitted through an annular portion coaxially disposed with the surface of the inspected part, and light rays reflected at the surface of the inspected part are received to form an image of the inspected part. The i...
