Area of Science:

Optical Engineering
Image Stabilization Technology
Freeform Optics

Background:

Image blurring and degradation occur due to relative movement between imaging systems and objects.
Existing optical stabilization methods may have limitations in correcting complex aberrations.

Purpose of the Study:

To propose and demonstrate an image stabilization optical system utilizing deformable freeform mirrors.
To correct image blurring and degradation caused by relative motion between the imaging optical axis and the object.

Main Methods:

Utilized Fermat's principle and matrix methods to model the optical path.
Calculated deformable mirror surface profiles based on constant optical path length and object-image point correspondence.
Employed off-axis three-mirror anastigmats for demonstration.

Main Results:

Developed a method for dynamic ray set coupling in object and image space.
Successfully demonstrated optical image stabilization using one- and two-deformable mirrors.
Showcased the system's ability to correct image degradation from object plane shifts.

Conclusions:

Deformable freeform mirrors offer an effective solution for optical image stabilization.
The proposed method provides a robust approach to counteract image blurring in dynamic scenarios.
This technology has potential applications in various imaging systems requiring high-fidelity image capture.
