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.
Scoring Rationale
Practical calibration methods aid SLM holography, but niche optics focus and preprint status limit broader impact.
