摘要（英）：

The invention discloses a probe used for measuring hypersonic speed air flow parameters. The probe comprises a stagnation chamber provided with an air inlet and an air outlet, and further comprises a measurement light incidence hole arranged on a side wall of the stagnation chamber, a fiber collimator which is mounted in the measurement light incidence hole and is used for introducing incidence light of a measurement system, a measurement light outgoing hole which is arranged on the side wall of the stagnation chamber and is separated with the measurement light incidence hole, a focusing lens which is mounted in the measurement light outgoing hole to couple with outgoing light to enter fiber of the measurement system, and a first reflection lens which is mounted on an inner side wall of the stagnation chamber and is arranged opposite to the measurement light incidence hole. The invention further discloses the measurement system and a measurement method. Compared with the prior art, the probe, the system and the method are advantaged in that the hypersonic speed air flow parameters can be acquired in real time, measurement precision is higher, a temperature measurement scope is larger, and a response speed is faster.
