New paper in Optics Communications with a new technique to distinguish between ordinary and extraordinary axes in a retarder layer
We published a new paper in Optics Communications entitled «Simple spectral technique to identify the ordinary and extraordinary axes of a liquid crystal retarder«.
In this work we analyze the effective retardance changes that happens when a retarder is tilted and use this effect to easily identify the ordinary and extraordinary axes of a liquid-crystal retarder by means of a spectrometer.
This work has been done in collaboration with our colleagues Juan Campos, from UAB, and Asticio Vargas and Aaron Cofré, from UFRO (Chile).
