An apparatus and method of visulazing target objects in a fluid-carrying pipe

摘要

An apparatus for recording and displaying images of and identifying material types in a target object in a fluid carrying conduit includes a downhole unit. The downhole unit includes a controllable light source, the controllable light source structured to emit high energy photons. The downhole unit further includes a sensor unit structured to detect the high energy photons that are backscattered from the target object and to generate signals in response to the detected high energy photons. The apparatus also includes a control and display unit that includes a signal transmitter and a viewing screen structured to display at least one two-dimensional image that is generated using the signals from the sensor unit.
