4.2 Public Beta Release, Imatest Events

Imatest version 4.2 is now available as a public beta. Join our Beta Test Group to access 4.2 updates. Highlights include:

  • SFRreg Module: Analyze the SFR of slanted edges through the automatic
     

    detection of registration mark patterns (circles with two light and two dark quadrants). Use arrays of registration mark targets to test unique imaging systems, including systems with ultra wide angle fisheye lenses (>180 degrees), multiple camera combinations, video and more.

 
  • Point Spread Function (PSF): Imatest can now estimate an imaging system’s loss of resolution (PSF)
     using a pair of collocated, near-sagittal and tangential slanted edges on SFRplus, eSFR ISO and SFRreg targets. Easily analyze and improve sharpness, chromatic aberration, and distortion measurements.
