Structure Distortion Measurement
Southern Research Institute has developed a unique facility for measuring structure distortion in air from 275 K to 350 K. Distortions due to isothermal, thermal gradient and load changes are monitored with 0.05 arc-second precision using an autocollimator to measure relative tilt between targets on the part.
