stress birefringence
Birefringence of materials that is induced or altered by stress fields.
stress corrosion
A type of fatigue found in optical fibers, caused by water or another corroding agent.
stress-applying part
In polarization-preserving optical fibers, the element used to induce birefringence. The SAP is highly doped to provide a different coefficient of expansion from the rest of the fiber material; when...
stressed mirror polishing
A method of polishing an aspheric surface by mechanically distorting the optic while polishing the surface to a perfect sphere. When the stress is released, the substrate assumes the desired aspheric...
SAP
stress-applying part
sapphire optical fiber
Sapphire optical fiber is a type of optical fiber made from single-crystal sapphire, which is a form of aluminum oxide (Al2O3) that is highly transparent in the infrared region of the electromagnetic...
static fatigue
The application of a constant stress to an optical fiber.
strain
In optics, the mechanical tension, compression or shear in optical glass due to internal stress caused by improper cooling or annealing during manufacture of the glass or the subsequent working of...
strain measuring equipment
->
photoelasticity
The process of determining, with the aid of plane-polarized light, the stress distribution in materials under complex systems of loading.
