6.2mm Full-Image 3D Phase-Measurement Videoscope with Integrated Working Channel

Product Overview

The Sugia OmniScope F1 is the flagship quantitative-inspection platform in the OmniScope product line. It integrates structured-light 3D phase-measurement profilometry into a 6.2 mm articulating probe, generating full-image point clouds of the viewed surface at up to 1.2 million 3D measurement points per frame — a fundamental advance over dual-aperture stereo videoscopes that measure only at user-selected discrete points.

The phase-measurement engine projects a series of precisely structured fringe patterns from a digital micro-mirror device (DMD) projector integrated into the probe tip, adjacent to the imaging sensor. The patterns shift in known phase increments, and the console’s GPU computes a dense depth map from the per-pixel phase differences across the projected pattern sequence. The result is a quantitative 3D surface map with X/Y resolution matched to the sensor pixel grid and Z (depth) resolution of ±0.01 mm at a 15 mm working distance.

Critically, the F1 also integrates a 1.2 mm diameter working channel that runs the full length of the insertion tube and exits adjacent to the probe tip. This channel accepts standard 1.0 mm diameter NDT retrieval tools (magnetic pick-up, 3-prong grabber, hook, wire-loop basket) for foreign-object retrieval in engine modules and other confined cavities. No other 6.2 mm class videoscope on the market combines full-image 3D phase measurement with an integrated working channel.

Key Engineering Features

• Full-Image 3D Phase Measurement: DMD-based structured-light fringe projector in the probe tip; 1.2 million 3D measurement points per frame (matched to 1440 × 1080 sensor grid); Z resolution ±0.01 mm at 15 mm working distance; measurement time < 3 seconds per frame.
• Six Quantitative Analysis Modes: Surface profile along arbitrary spline, depth from user-defined reference plane, point-to-point 3D distance, area with surface-roughness statistics (Ra, Rz), pit/crater volume, and automated corrosion-pit cluster analysis (depth, diameter, aspect ratio, interaction distance per ASME B31G Annex A).
• Integrated 1.2 mm Working Channel: Continuous lumen from handpiece to probe tip; compatible with standard 1.0 mm NDT retrieval tools; enables simultaneous visual inspection and foreign-object manipulation without probe withdrawal.
• 3D Data Export Suite: Point cloud export in PLY, STL, and XYZ formats for direct import into metrology software (PolyWorks, Geomagic, GOM Inspect); measurement results export as CSV tables; 3D surface render with measurement overlay as PDF report.
• Dual GPU Architecture: NVIDIA Jetson Orin NX for real-time phase-map computation plus Intel Arc GPU for 3D rendering and measurement analysis; provides 15 fps live 3D preview while computing full-resolution measurements in the background.
