GNR FILTER: See beyond structural noise.
GNR filter (*) included in all SITAU models, reduces grain noise and improves flaw detection by increasing the signal to noise ratio.
GNR filter is an advanced image processing technique that reduces grain noise while preserving flaw indications:
• Real time: no PRF reduction.
• Simple operation: no user defined parameters.
• Reliable: no missed defects.
Specially designed for Fiberglass or Carbonfiber reinforced parts inspections and austhenitic steel welds and parts. A valuable tool for most applications.
• Stainless steel welding inspections.
• Wind-blades GFRP inspections.
• Aerospace CFRF testing.
GNR filter feature:
• Reduces grain noise.
• Improves contrast.
• Improves spatial resolution.
• Suppress grating lobes indications
(*)GNR Filter is based on the patent “Phase Coherence Imaging Technique” (PCT/ES09/070303)
