see with 4d. Metrology that integrates time and space.

measure in dynamic situations

Dynamic measurements ensure you can measure surface quality with high precision, even in an automated environment, or in the turbulence caused by a large separation between your part and the metrology system.

It means you can attach your metrology system to a robot and sample at high speed, or take a measurement of a surface that is changing under stress.

Industrial Challenges

Aerospace and Defense

Aerospace and defense contractors rely on 4D Technology’s dynamic laser interferometers and optical profilers for accurate measurements.

Aviation and Automotive

Part inspection for high value machinery like aircraft engines requires high-volume, in situ defect qualification using non-contact 3D imaging of features.


Medical applications and biological research present a challenging set of requirements for measurement systems, including constantly changing subjects, difficult environmental conditions, and stringent controls, particularly for in vivo measurement.

Optics Manufacturing

4D Technology dynamic laser interferometers enable precision measurement right on the factory floor, without vibration isolation.


Semiconductor manufacturers count on 4D measurement instruments to ensure quality throughout the manufacturing process.

Vision Systems

4D Technology’s camera products provide unique, polarization-based imaging for manufacturing, environmental sensing and image enhancement applications.
