Abstract
1,108,235. Measuring surface roughness and symmetry of bores. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Nov. 2, 1965 [Nov.10, 1964], No. 46381/65. Heading G1M, [Also in Division G2] An optical instrument for determining the internal dimensions of a tube comprises two optical systems arranged so that, when inserted in the tube, light passing through the first system is directed into the interior surface of the tube and thence through the second system, the two systems being mounted in tube inserts 12, 13 which are coupled together, the second system including an annular slit diaphragm 21 and being movable relative to the first along the axis of the tube so as to bring the diaphragm 21 into alignment with the light passing from the tube surface, the movement being effected by a micrometer which indicates the variations in the interior surface of the tube. As shown the first system comprises two annular lenses 15, 16 separated by an annular slit diaphragm 17 and housed in an annular passageway 18 of the upper tube insert 12. The second system comprises two annular lenses 19, 20 separated by the annular slit diaphragm 21 housed in the insert 13, the two inserts being coupled together by a pin 25. Light from a source 14 housed in the insert 12 is directed by the first lens system on to the interior of the tube under inspection. Light reflected therefrom passes through the second lens system and is reflected by a frusto-conical mirror 26 which directs the annular beam of light along the tube towards a photographic film, for example. Variations in the interior surface of the tube will require movement of the diaphragm 21 in the direction of the tube length until the slit of the diaphragm registers with the annular beam of light incident thereon. This movement is effected by rotation of a screwthreaded spindle 30 which engages a screw-threaded bore 45 in the insert 13 and abuts against a cylinder 28 which slides in the insert 13 and mounts the diaphragm 21. The spindle 30 is rotated by a micro-motor 29 on operation of a micrometer screw 32. In a second embodiment, the annular optical systems are replaced by linear projection systems, the inserts 12, 13 being arranged to rotate together so that a beam of light passing through the first lens system scans the interior surface of the tube.
