FIELD: physics.
SUBSTANCE: proposed device comprises cylindrical casing 1 with top and bottom openings 2 and 3. TV camera 3 with CCD-matrix is arranged behind top annular opening 2 to move along lengthwise axis of casing 1 and be locked depending upon controlled surface diameter. Annular light source 7 is arranged behind bottom annular opening 3. Casing is provided with drive 4 to move inside controlled surface 5. Sighting marks 8 and 9 are arranged atop casing 1 to stay in field of vision of second TV camera with CCD-matrix secured on controlled surface 5. Rocker 11 is arranged at casing bottom to move perpendicular to casing lengthwise axis and lock optical axis of TV camera 6 in vertical position.
EFFECT: automated measurement of inner vertical cylindrical surface irregularities.
