Abstract

A pointing system having a rotatable housing, a boresight relative to the housing, a rotatable mirror, and a laser emitting a beam of light, wherein the beam of light is redirected off the mirror to the pointing target. When the rotatable mirror is rotated, the beam of light is moved relative to the boresight. The system operates such that rotation of the beam of light by means of the rotatable mirror is greater than the rotation of the boresight by means of the rotatable housing.

Claims

1. A pointing system comprising:

a housing having an opening defining a boresight;

a moveable mount rotationally supporting the housing for rotation about at least one rotational axis;

a first driver operably coupled to the moveable mount to rotate the housing about the at least one rotational axis;

a laser provided within the housing and configured to emit a beam of light;

a mirror movably mounted within the housing to direct the beam of light through the opening; and

a second driver operably coupled to the mirror to effect the movement of the mirror;

wherein movement of the mirror moves the beam of light relative to the boresight.

2. The pointing system of claim 1 wherein the first driver operates at a first rate and the second driver operates at a second rate, which is faster than the first rate.

3. The pointing system of claim 2 wherein the first rate is a maximum rate for the first driver.

4. The pointing system of claim 1 wherein the mirror is movably mounted to rotate about the at least one axis of rotation.

5. The pointing system of claim 4 wherein the first driver operates at a first rate and the second drive operates at a second rate, such that the laser is rotated at a faster rotational rate at the second rate than at the first rate.

6. The pointing system of claim 1 wherein the moveable mount rotationally supports the housing for rotation about two axes of rotation.

7. The pointing system of claim 6 wherein the moveable mount rotationally supports the housing for rotation about three axes of rotation.

8. The pointing system of claim 7 wherein the moveable mount comprises a gimbal mount supporting the housing.

9. The pointing system of claim 8 wherein the mirror comprises a mirror mounted to a hinge.

10. The pointing system of claim 9 wherein the second driver comprises a semiconductor chip supporting the hinge.

11. The pointing system of claim 1 wherein the mirror comprises a mirror mounted to a hinge.

12. The pointing system of claim 11 wherein the second driver comprises a semiconductor chip supporting the hinge.

13. The pointing system of claim 1 wherein the beam of light is at least one of pulsed and modulated.

14. A pointing system comprising:

a housing having an opening defining a boresight;

a rotatable mount rotationally supporting the housing for rotation about at least two rotational axes;

a laser provided within the housing and configured to emit a beam of light;

a rotatable mirror located within the housing to direct the beam of light through the opening and rotatable about at least one of the at least two rotational axes, wherein movement of the mirror moves the beam of light relative to the boresight.

15. The pointing system of claim 14 wherein the rotatable mount supporting the housing operates at a first rate and the rotatable mirror operates at a second rate, which is faster than the first rate.

16. The pointing system of claim 15 wherein the first rate is a maximum rate for the first driver.

17. The pointing system of claim 14 wherein the rotatable mount supporting the housing operates at a first rate and the rotatable mirror operates at a second rate, such that the laser is rotated at a faster rotational rate at the second rate than at the first rate.

18. The pointing system of claim 14 wherein the rotatable mount rotationally supports the housing for rotation about three axes of rotation.

19. The pointing system of claim 18 wherein the housing mount comprises a gimbal mount supporting the housing.

20. The pointing system of claim 14 wherein the beam of light is at least one of pulsed and modulated.
