The gas turbine engine is configured to ingest a first mass flow and to exhaust a second mass flow. The optically-based measurement system is configured to determine the first and second mass flows in response to performing an imaging process on the gas turbine engine.application/pdfenIn CopyrightIn-flight measured propulsion mass flow and thrust on aircraftPatentLowe, Kevin [0000-0002-0147-4641]12123313B2
