Abstract

A system for parallax correction includes a first lens having a first pin extending radially therefrom and a second lens positioned parallel to the first lens. A moving platform has a first slot for accepting the first pin therein. The first slot is angled relative to the lenses to correct for parallax between the first and second lenses. The system can include an actuator for extending and retracting the moving platform towards and away from an object to focus on the object.

First claim

What is claimed is:

1 . A system for parallax correction, comprising:
a first lens having a first pin extending radially therefrom; a second lens positioned parallel to the first lens; and a moving platform having a first slot for accepting the first pin therein wherein the first slot is angled with respect to the lenses to correct for parallax between the first and second lenses.

2 . The system of claim 1 , further comprising a second pin extending radially from the second lens and a second slot in the moving platform for accepting the second pin therein, wherein the second slot is parallel with an optical axis of the second lens such that the first slot is angled towards the second slot.

3 . The system of claim 1 , further comprising an actuator for extending and retracting the moving platform towards and away from an object to focus on the object.

4 . The system of claim 3 , wherein the first slot directs the first lens closer to the second lens as the moving platform extends along the optical axis to correct for parallax between the first and second lenses.

5 . The system of claim 1 , wherein the first slot is angled twenty degrees towards the second slot.

6 . The system of claim 1 , further comprising a fixed platform disposed beneath the moving platform wherein the fixed platform has a first fixed slot for accepting the first pin therein and a second fixed slot for accepting the second pin therein.

7 . The system of claim 6 , wherein the first fixed slot is substantially identical to the first slot and the second fixed slot is substantially identical to the second slot.

8 . The system of claim 7 , wherein the first pin extends from the first lens through the first slot of the moving platform to first fixed slot of the fixed platform, wherein the second pin extends from the second lens through the second slot of the moving platform to the second fixed slot of the fixed platform.

9 . The system of claim 1 , wherein the first lens is a long wave infrared lens and the second lens is a short wave infrared lens.

10 . A method for correcting for parallax, the steps comprising:
extending a moving platform towards an object to focus on the object, the moving platform having a first lens and second lens coupled thereto; and directing a first pin of a first lens within a first slot of the moving platform, wherein the first slot is angled to correct for parallax between the first and second lenses.

11 . The method of claim 10 , further comprising directing a second pin of the second lens within a second slot of the moving platform, the second slot being parallel to an optical axis of the second lens

12 . The method of claim 10 , wherein the first slot is angled towards the second slot.

13 . The method of claim 10 , further comprising activating an actuator to extend the moving platform towards an object.

14 . The method of claim 10 , wherein the first lens is a long wave infrared lens and the second lens is a short wave infrared lens.

15 . A system for parallax correction, comprising:
a first lens having a first pin extending radially therefrom; a second lens positioned parallel to the first lens; and a moving platform having a first slot for accepting the first pin therein wherein the first slot is configured to simultaneously direct the first lens parallel to an optical axis of the first lens and laterally with respect to the second lens to correct for parallax between the first and second lenses.
