Fig. 3. Sustaining fiber steady-state and dynamic responses to polarized light at varied e-vector angles. (A) The eye was exposed to continuous illumination and the e-vector was changed in a stepwise manner from the vertical (0°) at the left in four steps to horizontal (at t=25s, the lowest step on the polarization trace) and back to the vertical (modified from Glantz and McIsaac, 1998). (B) Sustaining fiber response to a changing e-vector. Polarizer rotation commences from a horizontal orientation at t=3.3s (start of the first rotation cycle) and undergoes 4.5 cycles of 180° rotation. Rotation is stopped at the vertical orientation.
