New paper published in Applied Optics with a novel automatic polarimeter design
We published a new paper in Applied Optics, entitled «Flexible polarimeter architecture based on a birefringent grating“. Here we present a novel optical setup useful for polarimetric measurements. It is based on a birefringent grating displayed onto a PAL-LCoS display. The system is compact and flexible, since the size of the image can be adjusted by means of the period of the grating. The system is made fully programmable by incorporating a variable LC retarder, whose orientation and retardance are optimized by means of the condition number indicator.
We made this work in collaboration with Asticio Vargas, Fabian Torres and Ramiro Donoso, our friend at Universidad de La Frontera, in Temuco, and with our friend Prof. Juan Campos from Universtat Autònoma de Barcelona.
