Abstract

Low coherence imaging systems are developed for studies of the living eye. Such systems employ light from a pigtailed superluminescent diode (SLD) that is injected into a single mode directional coupler. Light from one of the output ports is fed into a second coupler while the light from the other port is inserted into an index matching gel. This arrangement forms a Michelson interferometer. The system is used to obtain and display en-face images of the retina of areas 4�4 mm2 in less than 3 sec. Depth resolution is limited to 35 μm and transversal resolution is better than 30 μm. Overall measurement time can be reduced using multiple interferometers with different path imbalances to permit simultaneous display of images for different depths in the eye.
