Introduction

Features and Benefits

Detection - Particle analysis
Use the analytical functions to quantitatively detect and analyse thousands of image objects within seconds.  Particle detection supports the analysis of multi-phase objects.  For example, when porous material is being examined, both voids and grains can be inspected and classified simultaneously.  It is easy to verify the analytical results because the measurement results are linked to the particle within the image.

Automation

This add-in supports automated analysis sequences which are defined using the integrated "Automater" without any programming required.  Entire sequences of steps can be automated, from sample positioning and focusing, to image acquisition, image processing and evaluation, subsequent results display and archiving.  Frequently recurring tasks can thus be parametrised and executed at the click of a button.

Grains – Analysis of grain boundary

Analysing grain size using the intercept method is done via application of all standard norm intercept patterns.  Horizontal, vertical, diagonal, circular and combined line configurations are supported.  Grain-size is determined according to accepted national and international norms.  The basis for determining grain size is the mean intercept length.  Light or dark borders are detected for individual grain phases.  Stepped grain borders are detected for multi-phase materials.  Analyses of grain-border samples and samples with etched grain surfaces are supported.  Results appear in a sheet.

The planimetric measurement method determines grain size via the area of the grains. For automatic analysis, grain boundaries must be continuous – ie, unbroken.  To ensure that boundaries are continuous, the planimetric method includes a high-performance algorithm for reconstruction of grain-boundaries.  The planimetric method offers the opportunity for conducting analyses that go beyond the usual level of standard analysis: eg, bimodal g values, g values of sandwich layers, g-value histograms, elongation.  Thanks to integrated task automation, it is easy to define fixed task sequences for frequently recurring analysis tasks.  When using motorised stages, multiple samples can be analysed automatically – all in one step.

Cast iron – Analysis of cast

Cast iron is evaluated either automatically or manually.  Each graphite particle is automatically detected and evaluated with regard to shape and size.  Sheets and diagrams show size and shape distribution results.  Classifications according to various national and international standards such as VDG, EN ISO 945 or ASTM are integrated.  Other norms can be added by users.  In addition, determining the carbon-corrected ferrite/pearlite ratio is supported.  All evaluatory criteria and analytical settings can be saved and adjusted for use with various preparation techniques.

Fast Fourier Transformation (FFT)

Used to analyse frequency, FFT enables pattern recognition and the creation of special short/long pass filters to eliminate or preserve specific frequency ranges. A shortpass filter eliminates noise at high spatial frequencies, while a longpass filter passes high spatial frequency elements to obtain sharper or more clearly outlined images.

Programming

Imaging C is a programming language offering users a comprehensive programming environment.  This includes a program library with unrestricted access to the widely varied functions of analySIS FIVE as well as a debugging environment.
