Abstract: Systems and processes are provided for measuring carbon deposits on an engine. In some examples, a light source can be transmitted through a viewing window of an engine onto an area of an internal surface of the engine and reflected back through the viewing window and detected using an optical sensor. A topography of the area can be determined based, at least in part, on the reflected light source detected by the optical sensor and used to determine whether carbon deposits have increased, decreased, or remained constant on the area.
