Simultaneous optical coherence tomography and confocal imaging for retinal investigations

Techniques for simultaneous display of two en-face images of the retina, an optical coherence tomography image and a confocal image in pixel to pixel correspondence are presented. Such images are obtained from the eye using a fiberised low coherence interferometer and a bulk confocal receiver sharing the same galvanometer scanner and interface optics directing light to the eye. The images have different depth resolution and complement each other in the process of system adjustment and measurement
