Abstract

A method of correcting aberrations in an optical system by applying a light adjustable aberration conjugator layer to a component of the system, determining the nature of the aberration, applying radiation to the conjugator layer such as to change the refraction and/or shape of the conjugator layer to compensate for the aberration, and locking in the desired optical property.

Claims

1. A method for correcting at least one aberration in an optical system comprising:

providing a radiation adjustable layer to a component of the system;

determining the at least one aberration;

applying radiation to the radiation adjustable layer such as to modify an optical characteristic of the radiation adjustable layer to at least partially compensate for the at least one aberration; and

,

irradiating, subsequent to applying, the adjustable layer to lock in the modified characteristic;

wherein the adjustable layer comprises a radiation sensitive refraction modulating composition.

2. The method of claim 1 wherein the component is a refractive element.

3. The method of claim 1 wherein the component is a reflective element.

4. The method of claim 1 wherein the optical system is selected from the group consisting of:

a telescope, and a camera.

5. The method of claim 1 wherein the applying comprises:

generating the radiation with a vertical-cavity surface-emitting laser array.

6. The method of claim 5 wherein the applying comprises:

using an apodizing filter having a predetermined transmission intensity profile to form the radiation in a pattern.

7. The method of claim 1 wherein the applying comprises:

controlling the radiation during the applying.

8. The method of claim 7 wherein the controlling comprises:

controlling at least one of intensity and duration of the radiation.

9. The method of claim 1 wherein the radiation is ultraviolet light.

10. The method of claim 1 wherein the determining comprises:

using a Shack-Hartmann sensor to determine the aberration.

11. The method of claim 1, wherein the irradiating comprises:

applying a lock-in pattern that has a top hat intensity profile.

12. The method of claim 1, wherein the irradiating comprises:

applying a lock-in pattern that has an intensity profile that diminishes as the radius increases from the center.

13. A method for correcting aberrations in an optical system, comprising:

applying a light adjustable aberration conjugator layer, comprising a first polymer matrix and a refraction modulating composition dispersed therein, to a surface of a component of the system;

either before or after applying said conjugator layer, determining the nature of the aberration; and

applying radiation to the conjugator layer thereby polymerizing said refraction modulating composition such as to modify the refraction of the conjugator layer to compensate for the aberration.

14. An optical element, for correcting aberrations in an optical system, comprising a light reflecting or refracting element with a light adjustable aberration conjugator layer applied thereon, said light adjustable aberration conjugator layer comprising a first polymer matrix and a refraction modulating composition dispersed therein, said refraction modulating composition being polymerizable.
