Local variation in absolute water content of human and rabbit eye lenses measured by Raman microspectroscopy [PDF]

open access: yes, 1989
Raman spectra were obtained from fresh, fixed and sliced rabbit lenses and from human lens slices. For all lenses and lens slices the ratio R, defined as the Raman intensity at 3390 cm−1 divided by the Raman intensity at 2935 cm−1, was measured at ...

First-order Design of a Reflective Viewfinder for Adaptive Optics Ophthalmoscopy [PDF]

open access: yes, 2012
Adaptive optics (AO) ophthalmoscopes with small fields of view have limited clinical utility. We propose to address this problem in reflective instruments by incorporating a viewfinder pupil relay designed by considering pupil and image centering and ...
