4D Dynamic Laser Interferometer Applications

Dynamic Interferometry®, at the heart of all 4D products, overcomes many barriers to traditional, phase-shifting interferometry, such as moving parts, vibration, turbulence, etc. 4D has brought the power of dynamic laser interferometry to a wide range of applications, including large optics, general optics, data storage, optical storage pickup heads, and more.

Aerospace

Quality verification of electro-optical components and systems for tracking, surveillance and directed energy.

4D Technology’s dynamic interferometers provide metrology for Blu-Ray, DVD, and CD pickup heads, runout, velocity and acceleration (RVA) of hard disks, and double-side shape measurements of transparent media.

Astronomy

Shape measurement throughout the production of terrestrial and space-based telescope optics and systems.
4D Technology’s dynamic interferometers provide metrology for flatness, surface shape, surface character of large flat, convex and concave optics for terrestrial telescopes, space-based telescopes and directed energy systems

Optics Testing

Surface form and shape for flats, spheres, prisms, transparent optics, etc.

4D Technology’s dynamic interferometers provide metrology for quality and process control of optical elements including flats, spheres, aspheres, prisms, windows, mirrors, etc.

Data Storage

Process control for media flatness, RVA analysis, microwaviness, and wavefront quality of pick-up heads.
