LASER ROUGHNESS INDICATOR Russian patent published in 2006 - IPC G01B11/24 

FIELD: inspection of profile of items with complex shape.

SUBSTANCE: laser roughness indicator additionally has two objectives, which have optical axes disposed in plane formed by axes of lasers and by longitudinal axis of blade. Optical axes are disposed symmetrically at angles α to longitudinal axis of blade. Optical axis of TV camera's optical; axis coincides with axis of first additional objective. Beam splitter is mounted between the objectives. Reflector is mounted at cross point of optical axis of second additional objective with perpendicular erected from point of cross of reflecting face of beam splitter with axis of TV camera objective at plane of disposition of optical axes of additional objectives. Focal points of additional objectives are brought into coincidence with each other and with cross point of laser axes and with longitudinal axis of blade.

EFFECT: simplified design; improved metrological parameters.
