Optimization of Ultrasonic Parameters and Model Development for Nondestructive CTE Measurement of LAS Ultra-Low-Expansion Glass Ceramics

Lithium aluminosilicate (LAS) ultra-low-expansion glass ceramics are core materials for precision optical systems, whose quality and dimensional stability are critically constrained by the uniformity of the coefficient of thermal expansion (CTE). This work proposes a nondestructi...
