Olympus OmniScan MX PA Phased Array Instrument

Phased array technology generates an ultrasonic beam with the capability of setting beam parameters such as angle, focal distance, and focal point size through software. Furthermore, this beam can be multiplexed over a large array. These capabilities open a series of new possibilities. For instance, it is possible to quickly vary the angle of the beam to scan a part without moving the probe itself. Phased arrays also allow the replacement of multiple probes and even mechanical components. Inspecting a part with a variable-angle beam also maximizes detection regardless of the defect orientation, while optimizing signal-to-noise ratio.

Benefits of Phased Arrays

Phased array technology offers the following capabilities:

* Software control of beam angle, focal distance, and spot size
* Multiple-angle inspection with a single, small, electronically-controlled multielement probe
* Greater flexibility for the inspection of complex geometry
* High-speed scans with no moving parts

Phased Array Software

Full-Featured A-Scan, B-Scan, and C-Scans
OmniScan PA builds upon the OmniScan UT feature set and offers full-featured A-, B-, and C-scan displays.

Full-Featured Sectorial Scan
* Real-time volume-corrected representation
* Higher than 20 Hz refresh rate (up to 40 Hz)

Advanced Real-Time Data Processing
* Real-time data interpolation to improve spatial representation of defects during acquisition of data
* User-selectable high- and low-pass filters to enhance A-scan and imaging quality
* Projection feature allows the operator to view vertically positioned A-scan simultaneously with sectorial scan image.

Calibration Procedures and Parameters
All calibration procedures are guided by a step-by-step menu using Next and Back navigation.

Wizards for Groups and Focal Laws
* The Group Wizard allows you to enter all probe, part, and beam parameters, and generate all focal laws in one step instead of generating them with each change.
* The step-by-step approach prevents the user from missing a parameter change.
* Online help gives general information on parameters to be set.
