DynaPhase® Dynamic Acquisition Technology

Watch: DynaPhase™ dynamic data acquisition

Often, optical systems must be tested in locations that simulate their end-use environment. These environments can present challenges due to factors like large vibration and air turbulence, which can negatively affect or prevent the ability to acquire reliable optical measurements. Many of these challenges are addressed with less than optimal solutions, often suffering from drawbacks and issues related to usability, speed, reliability, and precision.

DynaPhase offers the versatility and performance to address a wide range of challenging optical testing environments and applications like cryogenic and vacuum chamber testing or telescope components and tower applications with long path lengths.

Key attributes of DynaPhase include:

  • Highest vibration tolerance in a Fizeau interferometer, enabled by the ZYGO-manufactured high-power laser and fast acquisition speeds
  • Patented in-situ calibration enables the highest precision, lowest uncertainty measurements, and excellent correlation to temporal phase shifting interferometry (PSI)
  • Simple setup and calibration compared to alternative approaches
  • Cost-effective solution; available on nearly all ZYGO laser interferometers
