  • Surface profile measurement system
    Patent number: 10267725
    Abstract: Apparatus for measuring surface profiles within passages such as the interiors of pipes, tubing, casing or the like includes an optical scanning system that acquires digital data that directly identifies the surface profiles. A temperature control system facilitates operation in high temperature environments. The optical scanning system may include a camera located between a light source and a conical mirror. Light deflecting elements may guide light from the light source to the conical mirror along a path that reverses direction.
    Type: Grant

  • Hand-held surface profiler
    Patent number: 8035823
    Abstract: A light-emitting hand-held surface profiler for scanning and profiling the surfaces of objects has a transparent housing, a focusable light source, a conical mirror aligned to redirect light emitted by the light source onto a surface to be profiled, an imaging sensor and a lens aligned to redirect toward the imaging sensor light reflected by the surface onto the lens. The light source, conical mirror, imaging sensor and lens are mounted within the housing and positionally referentially coupled to the housing.
