PhaseCam 5031

The PhaseCam 5030 from 4D Technology is an interferometer to measure optics for terrestrial and space-based telescopes. Unlike traditional, phase-shifting interferometers, the PhaseCam uses dynamic interferometry to acquire all measurement information in a single exposure, enabling measurement in the presence of vibration and air turbulence.

The system is remotely operated, for permanent mounting in measurement towers, environmental testing chambers or other locations with restricted access

The PhaseCam 5030 includes a high-speed optical phase sensor that eliminates the need for slow, piezo-based phase-shifters, allowing the system to measure more than 10,000 times faster than a conventional, phase-shifting interferometer. Because of this near-instantaneous measurement speed, the PhaseCam is virtually immune to environmental noise, alleviating the need for vibration isolation systems. Measurement averaging software overcomes the effects of air turbulence, for highly accurate measurements even when the system is located tens of metres from the test piece.

The turnkey PhaseCam system includes the interferometer, a high-speed computer system and extended-length cables for remote operation. 4Sight analysis software, included with the PhaseCam, provides extensive 2D and 3D analysis options, as well as comprehensive data filtering, masking, database and import/export functions.
