What Does IBR Stand For?
IBR stands for In Plane Birefringence
In Plane Birefringence (IBR) refers to the optical phenomenon where a material exhibits different refractive indices along different in-plane directions. This results in the splitting of light into two beams when it passes through the material, each traveling at a different speed and experiencing distinct polarization states. IBR is significant in various applications, including optical devices, material characterization, and stress analysis in engineering, where understanding light behavior within anisotropic materials is crucial.
