MTF MEASUREMENT WITH FastMTFTM

With Eidolon's MS-Windows 2000 based FastMTF software, the 2-D modulation transfer function can be acquired at sub-second rates.  FastMTF features tabular and color graphic MTF output updated in real-time to provide fast and accurate determination of the best focus MTF.  FastMTF's continuous MTF measurement capability can be used to provide real time feedback during the assembly and alignment of optical systems. Measure geometric distortion, LOS and boresight error in real-time too.


  STANDARD COMPUTER CONFIGURATION:
