FIGURE 3. Example of a two system combination, whole eye OCT system.21.
In this research system, there are effectively two separate OCT systems running simultaneously that share a final optic before the eye. In the system diagram on the left, the red path is a longer wavelength anterior segment system with optical path appropriate for focusing on the anterior segment. The green path is a shorter wavelength retinal system with optics designed to scan and focus on the retina. Representative images from this system are shown on the right (top is an eye undergoing accommodation with resultant smaller pupil and thicker lens while the bottom is the same eye dis-accommodated).
