Standard compliant determination of grain size by image analysis.
The dhs analysis module grain Size uses greyscale determination to detect the particle grain sizes contained in the structure via the "linear intercept method". This method is used for single-phase-ferrite and two-phase-ferrite/perlite structures, and for colour etchings.
To obtain meaningful results, you can analyse several micrographs or subsections of a specimen. The results are collected and shown in a freely configurable results table. The standards-compliant evaluation is performed as per DIN EN ISO 643 and ASTM-A247. Client-side settings can be saved in profiles to generate reproducible analyses.
For percental phase determination of materialographic specimens. The dhs analysis module Area Detection uses greyscale detection (phase analysis) to enable automatic detection, calculation and visualisation of area ratios. The different colours of the image (structural constituents) are converted into greyscale values and analysed in up to 6 phases or layers (entire image or a pre-selected section). Client-side options such as greyscale range, phase designation, border correction, etc., as well as a directly linked, automatic MS Excel™ evaluation, enhance the performance scope.
The dhs software module Measurement Tool enables two-dimensional measurement and labelling of previously saved images. With its innovative multilayer technology and many convenient features, it is used for a wide variety of applications.
You can connect a large number of different image sources to the dhs Image Data Base: from the digital microscope cameras which are commonplace today (see the dhs-MicroCam range) to simple analogue video cameras (b&w or colour), scanners, digital photo cameras and scanning electron microscopes, through to X-ray machines and interferometers.
Image-related data can already be entered directly during image capture. The process is supported by a function key. A large and fast live image ensures perfect ergonomics on the monitor.
