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.

A method for correcting aberrations in an optical system, comprising:
- applying a light adjustable aberration conjugator layer to 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 such as to modify the refraction of the conjugator layer to compensate for the aberration.
An optical element comprising a combination of a light refracting or reflecting element and layer thereon of a light adjustable aberration conjugator.
A method for correcting aberrations in an optical system, comprising:
- applying a light adjustable aberration conjugator layer to a component of the system;
- either before or after applying said conjugator layer, determining the nature of the aberration;
- and
- using an ultraviolet vertical-cavity surface-emitting laser array to generate a pattern that corresponds to the correction of the aberration and project it onto the surface of the conjugator layer so as to modify the refraction of the conjugator layer to compensate for the aberration.
A method for correcting aberrations in an optical system, comprising:
- applying a light adjustable aberration conjugator layer to 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 in a pattern obtained by projecting ultraviolet light through an apodizing filter having a predetermined transmission intensity profile that corresponds to the correction of the aberration such as to modify the refraction of the conjugator layer to compensate for the aberration.
A method for correcting aberrations in an optical system, comprising:
- applying a light adjustable aberration conjugator layer to a component of the system;
- either before or after applying said conjugator layer, determining the nature of the aberration;
- applying radiation to the conjugator layer such as to modify the refraction of the conjugator layer to compensate for the aberration;
- and
- irradiating the entire conjugator layer with locking radiation having a “top hat” intensity profile, to lock in the modified refraction.
A method for correcting aberrations in an optical system, comprising:
- applying a light adjustable aberration conjugator layer to a component of the system;
- either before or after applying said conjugator layer, determining the nature of the aberration;
- applying radiation to the conjugator layer such as to modify the refraction of the conjugator layer to compensate for the aberration;
- and
- irradiating the entire conjugator layer with locking radiation having an intensity profile that diminishes as the radius across the conjugator layer increases, to lock in the modified refraction.
A method for correcting aberrations in a reflective telescope, comprising:
- applying a light adjustable aberration conjugator layer to a surface of a mirror component of the reflective telescope;
- either before or after applying said conjugator layer, determining the nature of the aberration;
- and
- applying radiation to the conjugator layer such as to modify the refraction of the conjugator layer to compensate for the aberration.
A method for correcting aberrations in an optical system, comprising:
- applying a light adjustable aberration conjugator layer to a component of the system;
- either before or after applying said conjugator layer, determining the nature of the aberration;
- and
- applying aberration compensating radiation to the conjugator layer in a pattern that corresponds to the correction of the aberration such as to modify the refraction of the conjugator layer to compensate for the aberration, aberration compensating radiation having an intensity profile that changes as the radius of the pattern increases.
