Spatial Light Modulator Achieves Calibrated Far-Field Holograms
3.9
Researchers led by Markus Zimmermann (submitted Feb 4, 2026) use camera-in-the-loop calibration to calibrate a phase-only spatial light modulator in a far-field holography setup. The measured intensity distributions closely match calculated results, indicating precise calibration and modeled dominant aberrations. The paper quantifies how including or excluding aberration corrections affects image quality, diffraction efficiency, and speckle contrast.
Key Points
- 1Demonstrates camera-in-the-loop calibration of phase-only SLMs achieving measured intensities matching calculations
- 2Models dominant optical aberrations to improve calibration precision and account for diffraction efficiency changes
- 3Provides guidance on including/excluding aberration corrections to optimize image quality and speckle contrast
Scoring Rationale
Practical calibration methods aid SLM holography, but niche optics focus and preprint status limit broader impact.
