A fiberized optical coherence tomographic (OCT) system is modified to produce a confocal image similar to that produced by a scanning laser ophthalmoscope. Two possible configurations are presented, one that can deliver either an OCT or a confocal image and another that is capable of producing both the OCT and the confocal images simultaneously. Using the later configuration, we demonstrate such images from the retina in the living eye. The penalty in terms of performance reduction introduced into the optical coherence tomograph when integrated with a confocal receiver and the signal-to-noise ratio analysis for the different confocal receiver configurations are presented.
