Flexible Phased Array Configurations

The TomoView™ Advanced Calculator is an essential and powerful component of the TomoView software package. This calculator easily and precisely programs angle beams and focal points for 1-D Linear array, 1-D Annular array, and 2-D Matrix array probes, with its preprogrammed wedge, probe, and material database.

The Advanced Calculator can be used to program sectorial, linear, and depth scan focal laws for plane and circular geometries, supports dynamic depth focusing (DDF), and can also be used to generate OmniScan™ compatible law files (.law).

In addition, the graphical display of the resulting beams and angle beams provides you with an important validation tool. The Acoustic Field Simulation Module is available as an option, offering the simulation of spatially diffracted fields in 2-D or 3-D.

The Dynamic Depth Focusing (DDF) technique dynamically changes beam forming on reception for increased resolution, therefore allowing improved defect resolution while maintaining optimal inspection speed.

The Conditional A-scan allows the A-scans to be recorded only when an alarm is triggered. This allows the A-scans to be contained only in the areas where this information is important, allowing the user to inspect much larger areas in a single inspection.

With many new functions, TomoView 2.10 is now more than ever the best tool to take your analysis to the next level.

Maximum data file size has been increased to 2 GB, allowing you to merge data from multple files and analyze data from larger surfaces more efficiently.

Volumetric merge for improved data representation and effective analysis of multiple volumetric views in combined displays.

With its advanced analysis algorithms, TomoView 2.10 allows you to go even further with your acquisition data.

Powerful noise-analysis feature allowing you to quantify the signal-to-noise ratio and obtain more information about the inspection conditions.

Comprehensive matrix filters feature allowing better C-scan data representation in noisy environments.

TomoView's data file merging feature allows multiple data files to be combined into a single file, and then analyzed simultaneously, making the analysis process much more efficient.

TomoView 2.10 also allows up to 2 GB per data file, giving you the power to combine even more data files into a single one than before.

The C-Scan merge feature allows data from different C-scan patches to be merged in a single C-scan, where either the maximum or minimum amplitude or positions detected over the different C-scans are retained.

TomoView Volumetric Merging feature allows different acoustic beams to be merged in a single group, therefore providing a clear representation of the entire inspected part, making indication analysis much easier.

When spatial overlap occurs, the maximum amplitude is conserved. The merged view therefore shows all detected indications regardless of the original indication orientation.

Note that the indicators can differ due to the merge resolution used.

Signal-to-Noise Ratio tool

TomoView includes a signal-to-noise ratio (SNR) function. You can use the SNR Analysis Utility to evaluate the noise level in a reference area on a C-scan view, and then to calculate the indication surface area above the noise.

The SNR function is available in Analysis mode and with the Lite Aero edition. The SNR function is used for 0-degree inspections, often for aerospace industry parts. You can use the function on Top (C), amplitude, and position C-scan views.

Easy Reporting Tools

Creating a report in TomoView™ has never been easier. Use the Zone tool to add an indication. Select your preferred indication table template (easily customized with additional readings and comments). Click Add. Repeat for all relevant indications.

Changing company logos and adding inspection specific information (operator's name, site, part, etc.) can be done very easily, and a full html report including all relevant inspection settings can be created in a matter of seconds.

Once completed, indication tables are automatically saved in an .R01 file format, to be later uploaded into TomoView.

TomoView and the libraries give you the perfect tools to build flexible train wheels and axles inspection systems.

The NDT Data Access Library is a software development kit, which allows you to read data files using a custom application. It is especially useful in applications where it is required to visualize and process data acquired using Olympus instruments with custom procedures.

The Data File Access Library provides high-level access to data that normally prevents users from dealing with the complex architecture of the data files. Data and parameters related to data interpretation can be easily read (refracted beam angles, velocity, delays, offset, etc.).

The NDT Data Access Library offers direct access to the raw acquisition data from the source data file, allowing you to retrieve the amplitude, position, and thickness values acquired during the acquisition.

The NDT Data Access Library also allows you to retrieve the most important inspection parameters, therefore giving you the power to process and represent them based on your requirements.

The NDT Remote Control Library is a software development kit, which allows you to develop a special user interface for automated inspections using Olympus NDT instruments (phased array or conventional UT). From an external computer, the library can be used to directly control the TomoView™ software, offering a wide range of possibilities in both inspection and analysis modes.

Using the NDT Remote Control Library, you can create a custom program which can be used to send remote commands to TomoView. These commands can be used for on-the-fly setup modification as well as process optimization.

These remote commands can be sent from a local or remote computer. An open access is given through the RCLIB to the most commonly used features in acquisition and analysis.

The TomoView window can be directly embedded in any custom programmed frame, allowing you to create your own interface in which TomoView will be integrated. You can access the interface directly by clicking in its window.

With the advanced flexibility of the TomoView display, integrate only the panes containing the data that you want to present, therefore making the integration flawless.

The NDT Remote Control Library can also be used to obtain direct access to the live acquisition data, thereby allowing you to make custom processing or storage procedures directly from the raw data.

This feature can also be used to create custom alarm triggering criteria which can be easily interfaced with your system components.
