Modeling the rabbit's eye with the Mueller matrix for birefringent properties

“…The lens, component (6), expands the beam to cover the whole corneal surface. The traversing beam then propagates through the detection optical train, components (8)- (10), which consist of the same components as in the input optical train but in reverse order, with the polarizer, component (10) set at -45 °(M-state), before being imaged by a 14 bit, 509 X 511, TE-cooled CCD camera (Apogee, Auburn, CA). For further details of the automated Mueller matrix imaging system used, the reader is referred to cited reference no.…”

“…iris, retina, lens. [10][11]13 For our geometry (see Figure 1), where we couple light to laterally traverse the anterior chamber of the eye from the tear duct to the opposite edge where the upper and lower eyelids meet, these models are insufficient. Consequently, for this paper, we present preliminary data collected from an excised rabbit cornea that will enable us to characterize the apparent relative spatial variations in corneal birefringence and, thus, potentially enable us to optimize our system.…”

“…The birefringence of the eye is well documented in literature and numerous investigators have studied and developed models for corneal birefringence. 3,4,5,6,7,8,9,10,11 Unfortunately for us, these models are based on the transmission of light through excised and fixated cornea in vitro, [3][4][5][6][7]12 or by in vivo imaging of back reflected light that has traversed through the apex of the cornea and reflected off the inner structures, e.g. iris, retina, lens.…”
