About this technology

Overview

NASA worked with 4D Vision Technology- later acquired by Tucson, Arizona-based 4D Technology Corporation- to develop interferometers that could test large space mirrors. 4D created dynamic interferometry and enhanced the technology for optics, astronomy, aerospace, data storage, university research, manufacturing, and medical industries. The company has grown from 4 employees to more than 30.
