[0026] Please refer to figure 1 The optical path diagram of the reflective off-axis optical coupling device of the streak camera is shown, and the specific implementation method is as follows:
[0027] The optical path of the reflective off-axis optical coupling device of the streak camera is composed of a collimating mirror 11 and a focusing mirror 12 . The slit 13 is placed on the focal plane of the collimating mirror 11, so that the divergent light emitted from the slit 13 irradiates the collimating mirror 11 and is converted into parallel light. And it is required that the slit 13 is located outside the optical axis of the collimating mirror 11 to ensure that the light beam is not blocked by the focusing mirror 12 before reaching the collimating mirror 11 . The parallel light collimated by the collimating mirror 11 is irradiated onto the focusing mirror 12 , after passing through the focusing mirror 12 the parallel light becomes converging light, and finally irradiates on...
