Example 1

The first end switch 13, the second end switch 14 and the third end switch 15 are all in the closed state. The light beam enters from the light-entering collimator 5, passes through the glass tube 7, is refracted by the right-angle prism 8, and then sequentially passes through the first end chip 10, the second end chip 11 and the third end chip 12, and since the first end switch 13, the second end switch 14 and the third end switch 15 are all in the off state, the light beam is transmitted when passing through the first end chip 10, the second end chip 11 and the third end chip 12. At this time, the light beam passes through the glass tube 7 and the refraction of the right-angle prism 8, and then exits from the fourth exit collimator 4.

Example 2

The first end switch 13 is in an open state. The light beam enters from the light-entering collimator 5, passes through the glass tube 7, is refracted by the right-angle prism 8, and then passes through the first end chip 10. Since the first end switch 13 is in an open state, the light beam is refracted while passing through the first end chip 10. The light beam is refracted and then emitted from the first light-emitting collimator 1.

Example 3

The first end switch 13 is in the off state and the second end switch 14 is in the on state. The light beam enters from the light-entering collimator 5, passes through the glass tube 7, is refracted by the right-angle prism 8, and then passes through the first end chip 10. Since the first end switch 13 is in the off state, the light beam is transmitted when passing through the first end chip 10; after the light is transmitted, the light passes through the second end chip 11, and the second end switch 14 is in an open state, so that the light beam is refracted when passing through the second end chip 11. The light beam is transmitted through the first end chip 10, refracted at the second end chip 11, and then emitted from the second outgoing light collimator 2 after being refracted.

Example 4

The first terminal switch 13 and the second terminal switch 14 are in the off state, and the third terminal switch 15 is in the on state. The light beam enters from the light-entering collimator 5, passes through the glass tube 7, is refracted by the right-angle prism 8, and then passes through the first end chip 10. Since the first end switch 13 and the second end switch 14 are in the off state, the light beams are transmitted when passing through the first end chip 10 and the second end chip 11; after the light is transmitted, the light passes through the third end chip 12, and the third end switch 15 is in an open state, so that the light beam is refracted when passing through the third end chip 12. The light beam is transmitted when passing through the first end chip 10 and the second end chip 11, is refracted when passing through the third end chip 12, and is emitted from the third light-emitting collimator 3 after being refracted.

By controlling the first end switch 13, the second end switch 14 and the third end switch 15 to be turned on or off, the light beam is controlled to be transmitted or refracted when passing through the first end chip 10, the second end chip 11 and the third end chip 12, so that the light path is passed or turned off.
