Light Sheet Fluorescence Microscopy (LSFM / SPIM) L1-006
Unclaimed Principle — open for contribution
This Principle is declared in the catalog but has no reference solver, no pinned dataset, and is not registered on-chain. There is no reward pool. Submitting a cert against this Principle today will record the cert for reproducibility but pay zero PWM.
To claim it as a Bounty #7 contribution: open a PR adding (1) a reference solver, (2) ≥1 dataset pinned to IPFS, (3) updates to the L3 manifest with dataset CIDs. After verifier-agent triple-review, the founders' 3-of-5 multisig signs PWMRegistry.register() and the Principle becomes mineable.
Forward model E
Light Sheet Fluorescence Microscopy (LSFM / SPIM): light sheet illumination produces the measurement through a 4-node primitive DAG L.illumination.sheet -> K.psf.detection -> S.scan.axial -> int.temporal, with axial/z-step integration and Poisson signal noise + Gaussian read noise. Recovery is posed as a linear inverse problem that inverts the forward operator to estimate the scene-side 3D intensity. Difficulty tier delta=3 with effective condition number kappa_eff~10; calibration-level mismatch (sheet_thickness_nm, sheet_tilt, sample_induced_aberration) sets the accuracy floor at the Omega boundary. See the forward_model field for the closed-form imaging equation.

Existence of the recovered 3D intensity is guaranteed within the declared Omega bounds. Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is moderately conditioned (kappa_eff ~= 10); sheet_thickness_nm dominates the stability cliff; sheet_tilt and the remaining mismatch parameters contribute higher-order bias terms. Poisson signal noise + gaussian read noise sets the irreducible data-fidelity floor, while mild Tikhonov or analytic inversion is sufficient at the nominal Omega point.
