 OmniScan™ is the newest family of modular and portable test units from Olympus. This family includes the innovative phased array and eddy current array test units, as well as the newly introduced eddy current and conventional ultrasound modules, all designed to meet the most demanding requirements of NDT. The OmniScan offers a high acquisition rate and powerful software
features in a portable, modular mainframe to efficiently perform manual and automated inspections.
Rugged, Portable, and Battery-Operated
The OmniScan™ is built to work in the harshest field conditions. Its solid polycarbonate-based casing and rubber bumpers make it a rugged instrument that can withstand drops and shocks.
The OmniScan is so compact and lightweight (only 4.6 kg) that it can be carried easily and handled anywhere inside or outside. The OmniScan will run 6 hours with its two Li-ion batteries.
User Interface
The highly legible 8.4-inch real-time display (60-Hz A-scan refresh rate) with a SVGA resolution of 800 x 600 allows you to clearly see defects and details under any light conditions. A scroll knob and function keys make it easy to browse through and select functions. A mouse and a keyboard can also be plugged in for users looking for a more PC-like interface.
Modular Platform
The instrument is a modular platform that allows you to switch among its different test modules on location. The platform detects the new module and the technology supported so that the configuration and test environment are set automatically.
OmniScan Connector
The OmniScan connector has a probe ID feature that enables physical detection and recognition of the probe connected to the mainframe.
- Sets the probe to an appropriate frequency to prevent probe damage.
- Sets C-scan resolution of ECA probes.
- Loads the correct probe parameters.
Storage and Report- Setup storage compatible with Microsoft® Windows® (exportable using a CompactFlash® card)
- Complete report setup including reading configuration, which can be customized using HTML page layout
- On-screen interactive help that can be customized for procedure-oriented setups using HTML script templates
- Setup preview
Connectivity, Data Storage, and Imaging
The OmniScan™ offers alarm outputs as well as the standard PC ports: USB, RS-232, SVGA out, and Ethernet™. It offers internal data storage capability and extended storage via a CF (CompactFlash®) card slot or USB device.

Typical Applications
| Girth Weld Inspection
Olympus has developed a circumferential weld inspection system based on the OmniScan PA for the oil and gas industry. This phased array system is qualified to inspect tube with diameters ranging from 48 mm to 1524 mm and thicknesses from 5 mm to 25 mm in compliance with ASME Boiler and Pressure Vessel Code Section V. The semiautomated system offers better inspection speed and detection, and makes the interpretation of the indications significantly easier.
Inspection of Tee-Joint Welds on Bridge Structures
Automated welding used to build multiple parts of bridge structures can generate cracks in the upper part of the weld of thin stiffeners. The OmniScan allows simultaneous scanning from 40 to 70 degrees. Users can inspect the complete volume of the weld in a single pass. Compared to conventional UT, this technique enables an inspector, with a few hours of training, to operate at least five times faster and present more reliable results.
Landing Gear Inspection
The OmniScan allows the complete inspection of a critical section of the landing gear: a cylinder possessing three different diameters in the zone of interest. The inspection is done in a single pass with 40- to 65-degree shear wave refracted angles in the part. With this system, any inspector can perform the inspection faster, and with better reliability.
Aircraft Fuselage Inspection
The OmniScan ECA provides the ability to detect hidden corrosion in multilayer structures and especially in lap joints independently of lack of sealant. Currently, material loss of 10% of the lap splice thickness can be detected in aluminum at a depth of 0.2 inch. Surface and subsurface cracks can be detected in the skin, at the fastener, or at the lap joint edges.
