摘要： An apparatus for inspecting a selected target region in an interior cavity of a turbine engine rotor includes independent sources of ultraviolet and visible light for illuminating the selected target region, an arm having a working end translatable in a principal direction so that the working end is insertable into the rotor interior cavity, a primary camera mounted at the working end of the arm for capturing an image of the selected target region, a video monitor, and means for conveying the camera image from the primary camera to the video monitor. Ideally, the arm is also translatable in a secondary direction to facilitate positioning of the camera relative to the rotor. Suitable light guides convey the ultraviolet and visible light from their respective sources to the working end of the arm. A remote camera control, which is part of the camera electronics, allows an inspector to remotely focus the camera. An auxiliary viewing attachment with its own camera is reversibly securable to the working end of the arm for viewing surfaces angularly offset from the line of sight of the primary camera. The main components of the apparatus reside on a wheeled transport cart for easy portability.
