This study demonstrates how a 97-element Micro-Electro-Mechanical System deformable mirror (MEMS DM) effectively corrects wavefront aberrations. Adaptive optics (AO) using this MEMS DM improved image quality by approximately 30% in simulations and 28% in experiments.

Area of Science:

Optics and Photonics
Optical Engineering
Image Processing

Background:

Adaptive optics (AO) systems correct wavefront aberrations from optical systems or transmission media.
Deformable mirrors (DMs) are essential components in AO systems for aberration correction.

Purpose of the Study:

To analyze the image correction capabilities of a 97-element Micro-Electro-Mechanical System deformable mirror (MEMS DM).
To evaluate the performance of the MEMS DM in correcting blurred images of extended sources degraded by atmospheric turbulence.

Main Methods:

Utilized a 97-element MEMS DM for adaptive optics correction.
Employed the RUN optimizer as the control method for aberration correction.
Conducted both simulations and physical experiments to assess correction performance.

Keywords:

Main Results:

Simulations showed convergence of normalized gray variance and Strehl Ratio within 100 iterations, improving image quality by ~30%.
Physical experiments demonstrated an increase in normalized gray variance (NGV) from 0.53 to 0.97.
Experimental results indicated an improvement in Natural Image Quality Evaluation (NIQE) from 15.35 to 19.73, an overall image quality enhancement of ~28%.

Conclusions:

The 97-element MEMS DM effectively corrects wavefront aberrations in extended sources.
Findings provide theoretical and technical support for MEMS DM applications in adaptive optics.
This research contributes to improving imaging quality in the presence of atmospheric turbulence.
