Features

• Hologram computation using angular spectrum propagation and Fresnel transform.
• Time demodulation by short-time Fourier transform (STFT) and principal component analysis (PCA) algorithms.
• Graphical user interface (change parameters on the fly, keyboard shortcuts).
• Support the following cameras:
  • Ametek streaming cameras S710, S711, S991 interfaced with Euresys Coaxlink Octo & Coaxlink QSFP+ frame grabbers.
  • Adimec Quartz-2A750 interfaced with Bitflow CYT-PC2-CXP4 frame grabbers.
  • IDS imaging CMOSIS CMV 4000
  • Ximea CMOSIS XiQ and XiB
  • Hamamatsu C11440
  • Adimec Phantom S710
  • Adimec Phantom S711
• Import interferograms from .cine files.
• Import or export interferograms/holograms with .holo files.
• Modular configurations with .json files.
• Zone selection (zoom, signal/noise averaging, filtering).
• Many various parameters: logarithm filter, rotations, flips, ...
• Auto and manual contrast.
• Different view modes: magnitude, squared magnitude, argument, unwrapped phase.
• Batch savings (CSV).
• Batch output as raw images, controlling instruments with GPIB interface.
• Real time chart plot.
