Abstract
The present invention relates to a multiple channel optical mapping apparatus which can deliver one or simultaneously at least two images of different depth resolutions or sequentially, images with different depth resolutions, or a combination of these images, or a single image with adjustable depth resolution. The multiple channels could be either multiple confocal channel and one or two optical coherence tomography channel, or two optical coherence tomography channels, or two confocal channels. The channels, either OCT or confocal can operate on the same wavelength or on different wavelengths. The apparatus can display both transversal as well as longitudinal images in an object, particularly the eye.
