Superpixel Complex Amplitude Modulation Measurements at Three Wavelengths

Chenxiao Wei published a dataset containing measured superpixel complex amplitude modulation results at three wavelengths (638 nm, 520 nm, 450 nm). The data includes complex amplitude distributions (F_spR, F_spG, F_spB) across four phase coordinates for each wavelength, with coordinate ranges and step sizes specified. The dataset was last updated on 2026-05-20 and is available as a 15.9 MB CSV file under a CC-BY-4.0 license.

Use Cases

• Calibrating spatial light modulator (SLM) response based on measured complex amplitude distributions.
• Modeling optical superpixel behavior using four-dimensional interpolation of the provided phase coordinates.
• Comparing wavelength-dependent modulation performance (638nm, 520nm, 450nm) for multi-wavelength optical systems.

Strengths

• Provides complex amplitude measurements at three distinct wavelengths (638 nm, 520 nm, 450 nm).
• Includes detailed phase coordinate ranges and step sizes (e.g., π/4 steps) for precise interpolation.
• Dataset size is 15.9 MB, suggesting a detailed tabular structure.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The description notes an insufficient modulation range at 638nm, indicating a potential hardware limitation for that wavelength.
• Phase coordinate values are described as not strictly discrete, which may introduce interpolation complexity.
