Documented response scope: shared Sony IMX990/IMX991 family graph; no model-specific split or camera-level inference

Native channel samples

Each channel retains its source wavelength grid and values. The plot uses shared display axes; gaps and negative values remain visible. No normalization, interpolation, averaging, or resampling is applied.

Native samples on a shared display axis: 410–1650 nm, 0 to 0.996. Curves are not normalized, averaged, interpolated, or resampled.

Research details

Configuration

manufacturer: Sony
mode: sensor-family shared trace
models: ["IMX990","IMX991"]
variant: InGaAs SenSWIR family; manufacturer publishes one shared relative-QE trace

Method

axes: {"response":[0,1],"wavelength_nm":[400,1800],"x_pixel":[1147,1666],"y_pixel":[2009,1771]}
figure: Wavelength (horizontal axis) and Relative quantum efficiency (vertical axis) of IMX990/IMX991

max_column_search_radius_px: 0
max_observed_trace_width_px: 14
method: calibrated raster columns, median vertical center of color-threshold trace pixels; configured local column search checks offsets in nearest-first order where the nominal column cannot yield a unique continuity-consistent trace; where separated fragments occur, follow the nearest prior trace center, or use the unique widest fragment to initialize, and reject ties; preserve missing samples; no normalization, interpolation, or extrapolation

Uncertainty

Value: ["Trace is digitized from a manufacturer raster graph; source publishes no numerical point table.","The plotted quantity is explicitly relative quantum efficiency from 0 to 1; the separate >75% at 1200 nm scalar is not used to rescale it.","Manufacturer assigns one shared trace to IMX990/IMX991, so no separate model-level curves are claimed.","The source says data may vary with conditions and environment; test temperature, calibration, and measurement uncertainty are not specified.","Raster extraction tolerance describes plotted-pixel picking only and is not source measurement uncertainty."]
