Gauging of High-Temperature Samples (87)
Problem: Develop method to measure tube diameter and length during rapid, dynamic high-temperature tensile/pressure tests
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Integrated Systems
PNNL Solution:
- Developed optical gauging concept for sample temperatures 2000°F
- Used gauging system to reliably measure dimensions during fast ramp tests (rf heating, tube pressure, axial loads)
- NOTE: System provided accurate data that fully met project requirements
- NOTE: US patent awarded for evelopment of novel beam modulation/shaping scheme to allow superior edge detection capability
Capabilities Employed to Meet Client Needs: Optical physics with major emphasis on polarization effects; optical design including polarized optics and electro-optic polarization modulation; development of novel beam modulation/shaping scheme to allow superior edge detection capability; analog (f ; 100 MHz) and digital electronics design, fabrication, and installation; mechanical design for optical system packaging and for integration with tensile test system; software development for system control, data acquisition, and data analysis; lab test planning and analysis; system documentation; formal results reporting.
