Use of q-plate as a coupler.
Bansal S, Kumar Pal S, Senthilkumaran P. Bansal S, et al. Appl Opt. 2020 Jun 1;59(16):4933-4938. doi: 10.1364/AO.395728. Appl Opt. 2020. PMID: 32543490
The q-plate being a coupler and made of half-wave plate segments, the singularity index change is concomitant with the helicity inversion of C-points. Interconversion of bright and dark C-points is possible by using a q-plate....

Signal-to-noise ratio analysis of one- and two-channel halfwave plate polarimeters.
Wagner JW, Deaton JB Jr. Wagner JW, et al. Appl Opt. 1987 Jun 1;26(11):2240-4. doi: 10.1364/AO.26.002240. Appl Opt. 1987. PMID: 20489849
The theoretical shot-noise-limited signal-to-noise ratio (SNR) is compared for one- and two-channel halfwave plate polarimeters, where rotation of the halfwave plate within the system causes a corresponding rotation in the incident linear polarization. …
