Summary
We developed a compact super-resolution imaging system using total internal reflection and a digital micromirror device (DMD). This system achieves high-resolution, broadband polarization imaging with simultaneous capture of multiple polarization states.
Area of Science:
- Optical Engineering
- Imaging Systems
- Super-resolution Microscopy
Background:
- Super-resolution imaging requires advanced optical designs.
- Simultaneous polarization capture enhances image information.
- Aberration correction is crucial for high-resolution imaging.
Purpose of the Study:
- To propose a novel dual-aperture, simultaneous-polarization super-resolution imaging system.
- To achieve broadband, high-resolution imaging with a compact design.
- To effectively correct aberrations and suppress distortion.
Main Methods:
- Combined total internal reflection optics with a digital micromirror device (DMD).
- Utilized reflective Wassermann-Wolf differential equations and Seidel aberration theory for aberration correction.
- Introduced a custom merit function to minimize distortion.
Main Results:
- Achieved F/2.5 system aperture.
- Reduced grid distortion to below ±0.5%.
- Demonstrated near-diffraction-limited performance across all polarization channels.
Conclusions:
- The developed system enables robust, high-resolution polarization imaging.
- The design is compact and lightweight, suitable for various applications.
- Simultaneous polarization state capture with a single detector is feasible.
