ABSTRACT:
The engine spectrometer probe and method of using the same of the present invention provides a simple engine spectrometer probe which is both lightweight and rugged, allowing an exhaust plume monitoring system to be attached to a vehicle, such as the space shuttle. The engine spectrometer probe can be mounted to limit exposure to the heat and debris of the exhaust plume. The spectrometer probe50comprises a housing52having an aperture55and a fiber optic cable60having a fiber optic tip65. The fiber optic tip65has an acceptance angle87and is coupled to the aperture55so that the acceptance angle87intersects the exhaust plume30. The spectrometer probe can generate a spectrum signal from light in the acceptance angle506and the spectrum signal can be provided to a spectrometer508.
