Paper Abstract

In this work authors describe a new scanning laser ophthalmoscope (SLO) device, which allows the separation of the apparatus into two parts: one near the hear of the subject, the other far from the subject. A fiber optic double pass illumination/detection technique is used. Reflections coming from fiber facets are eliminated by: polarization, time-gated illumination/detection techniques and 8DGR angled facet. The SNR measured is 40. This device improves by 2 times the retina luminous level to noise luminous level ratio in comparison to conventional SLO. Double pass fiber optic SLO allows eye environment miniaturization, removes sources and detection devices far from patient, and improves image contrast.
