This full-field photoelastic strain measurement system features automated data acquisition and processing. The extremely sensitive system can measure shear strain magnitude and direction without high-strain photoelastic fringes. The GFP 1000 utilises Stress Photonics' DeltaVision software for detailed analysis and high quality presentation.
Key Features of the GFP 1000

Software
The full-field strain images can be analysed via the easy to use DeltaVision software. The software allows GFP 1000 users to take advantage of powerful Windows software and network resources to process and present data quickly and easily. DeltaVision works easily with popular word processing and graphic presentation software such as Microsoft Word and PowerPoint. Images and data information can quickly and easily be copied and pasted from DeltaVision to other Windows applications.
