Interferometry Laser Systems
  • wavefront In considering a field of electromagnetic energy emanating from a source, the wavefront is a surface connecting all field points that are equidistant from the source.
  • surface profile A representation of the shape of a surface, including any roughness or other irregularities. The profile can be generated by direct measurements, as by a stylus, or by remote measurement, as by an interferometer.
  • laser interferometer An interferometer that uses a laser as its light source. The purely monochromatic nature of the laser results in improved efficiency and overall performance.
  • interferometry The study and utilization of interference phenomena, based on the wave properties of light.
