Structure Optical Metrology Instrumentation Support

Orbital ATK has the expertise and experience to develop instrumentation and software for unique applications. Data from interferometers, autocollimators, temperature sensors, load cells, strain sensors, stepper motors, actuators and other Instrumentation can be integrated into a comprehensive software package for data acquisition and process control.

Orbital ATK has developed unique capabilities for measuring structure distortion using a suite of optical metrology capabilities complemented by custom instrumentation and software support. Distortions due to isothermal, thermal gradient and load changes are monitored with 0.05 arc-sec and 0.4 micro-inch precision using an autocollimator to measure relative tilt between targets and interferometers to measure displacement.

Applications include satellite structures, optical benches, and tube twist.
