Industry Verticals

Target applications: industrial quality assurance, semiconductor metrology, and precision optics. Edge-aware filtering is built for inspection tasks where sharp transitions matter.

Industrial Quality Assurance — Pilot Program

Advanced

Customer Challenge: 2D inspection systems cannot detect critical 3D defects including BGA failures, solder volume errors, and microvia depth variations.

Our Solution:

  • • 3D Solder Paste Inspection: Volume, area, height measurement before component placement (edge-aware detail preservation)
  • • BGA Standoff Measurement: Collapsed solder ball detection (SNR fusion: intelligent path weighting)
  • • Microvia Depth Verification: Non-contact laser-drilled hole measurement before plating (Zero-phase: <0.05 px drift)
Status Paid validation pilots now open

A second, independent measurement point alongside your AOI system, on data you already have. Paid validation pilots now open.

Semiconductor Manufacturing

Advanced

Customer Challenge: Wafer defects invisible to 2D inspection but critical to yield. Current metrology requires slow, expensive SEM or AFM.

Our Solution:

  • • Wafer Defect Detection: Pit, scratch and contaminant identification on bare silicon (Edge-aware for sharp feature detection)
  • • Etch Depth Metrology: Trench depth, feature height, sidewall angle measurement for process control (Zero-phase: no spatial drift)
  • • MEMS Device Analysis: Real-time 3D profiling of cantilevers, membranes, micro-gears (Block overlap-add: MSE <1e-15)
Deployment Model Enterprise integration

Off-axis architecture eliminates twin-image artifacts. SNR regime fusion optimizes dual-path processing. Non-destructive wafer inspection alternative to SEM.

Precision Optics

Advanced

Customer Challenge: Surface quality determines optical performance. Contact profilometry risks damage; interferometry expensive and slow.

Our Solution:

  • • Surface Roughness (Ra) Measurement: Non-contact topography of mirrors, lenses and optical flats (edge-aware filtering)
  • • Micro-Lens Array QA: Radius of curvature, uniformity, height measurement of lenslet arrays (Zero-phase filtering)
  • • Scratch/Dig Quantification: Precise depth/width measurement for MIL-SPEC or ISO compliance (Edge-aware detection)
Deployment Model Production metrology

Full-color RGB holography reveals coating defects invisible to monochrome systems. Edge-aware enhancement preserves critical surface features.

Medical & Life Sciences

Our Solution:

  • • Label-Free Live Cell Imaging: Phase shift measurement maps cell biomass and internal structure without staining
  • • Drug Response Studies: Time-series observation of living cells reacting to stimuli
  • • Medical Implant Surface QA: 3D roughness mapping for biointegration specifications

Verified Facts

Every statement in this section is backed by a committed, independently checkable artifact. Where a figure has no committed artifact, we publish no figure.

Software-Defined Calibration — live in production

Digital-twin calibration is live on the production API, including the no-account /public/reconstruct endpoint. In the committed closed-loop proof, the optimizer recovered the true pixel pitch to within 0.0005% from a nominal that was mis-specified by 6%, and the digital twin replicated the measured field to within the optimizer's convergence tolerance. This is a closed-loop synthetic validation of optimizer convergence and endpoint plumbing — not a physical-target measurement, and we label it as such. Artifact: calibration/results/sdc_end_to_end_hex_nut.json.

Deploy provenance you can query

The live /health endpoint serves a full deploy-identity block, and a hash-chained deploy ledger verifies intact from genesis. Both are registered live checks (deploy-identity, ledger-verify) — ask, and the running system answers with a live run.

Data-retention governance, fail-closed

Retention policy is class-keyed with fail-closed owner routing (unclassified data routes to a named data-integrity owner, never to a default), write-once legal-hold events with declared release conditions, and provable clock-basis divergence. Verified by the registered retention-proof check.

Conformity decisions are data, not code

Quality-threshold decisions ship as content-addressed, supersession-chained records with an enforced separation between the business decision owner and the engineering computation. The freeze gate requires at least three independent evidence lineages — a passing verdict cannot be self-manufactured by the vendor.

Benchmark discipline

Every published performance number is stamped with the committed result artifact it came from; capabilities without a committed measurement are listed as not-yet-benchmarked and carry no number. A freshness check (bench-doc) fails the build if the published document drifts from the artifacts.

Regression budget enforced at every release

A quiet-window benchmark-regression gate runs against a committed baseline with a fixed 0.80 performance budget before changes are accepted. The gate result is a registered live check (bench-regression).

Inline Configurations

Direct optical path: Emitter → Object → Sensor.

  • • Iris Aperture: Enables 5-10mm closer object placement for increased contrast
  • • Microscopy: 10mm pinhole-to-sample, 130mm sample-to-sensor (wide-field)

Off-Axis Configurations

Beamsplitter creates separate reference path; eliminates twin-image artifact.

  • • Compact: 200×150mm, 15-25° reference beam, 5-10mm object distance
  • • Large-format: 600×400mm, 10-15° reference beam, 100mm object distance, 60×45mm field

Distance Parameter Impact

Object-to-sensor distance determines resolution-field tradeoff.

  • • Close (5-15mm): High numerical aperture → micron-scale resolution, limited field
  • • Far (100-130mm): Lower numerical aperture → extended field, coarser resolution
  • • Software-Defined Calibration automatically corrects geometric variations
