1. A method of embedding a probe in an airflow passage within a gas turbine engine, the method comprising:
housing a first optical fiber within a support, the support in view of an airflow passage; housing a second optical fiber within a second support opposite the first optical fiber to define a beam across the airflow passage; and locating the support within an airfoil; wherein the gas turbine engine comprises a rotor blade within the airflow passage, and the rotor blade is operable to disrupt the beam across the airflow passage.
