Active Thermography (IR) — Public Tier

(3 scenes)

Full-access development tier with all data visible.

What you get

Measurements (y), ideal forward operator (H), spec ranges, ground truth (x_true), and true mismatch spec.

How to use

Load HDF5 → compare reconstruction vs x_true → check consistency → iterate.

What to submit

Reconstructed signals (x_hat) and corrected spec as HDF5.

Parameter Specifications

True spec visible — use these exact values for Scenario III oracle reconstruction.

Parameter Spec Range True Value Unit
emissivity_error 0.94 – 0.97 0.955 -
heat_source_power_drift 0.98 – 1.04 1.01 -
background_temperature 24.0 – 27.0 25.5 C
integration_time_offset -0.02 – 0.04 0.01 s
