More about 4D:
Remote Control Measurement

Measuring large optics with traditional phase shifting interferometers can be difficult and expensive. Their susceptibility to environmental noise demands thorough vibration isolation, rigid coupling to the test sample, and extensive measures for air turbulence reduction.

4D technology's PhaseCam dynamic interferometers measure even in the presence of significant vibration and air turbulence, allowing them to measure in difficult environments, many meters from large test optics, with little ...
