Abstract
Channel separation in ophthalmologic systems is achieved by introducing a small angle between each beam incident on the scanner. The multiple channels are emitted from multiple emitters positioned such that their respective beams reach an X-Y scanner with small angular separations between the beams. This removes the need for dichroic components to combine the multiple channels into a single beam. This also allows the emitters to use the same wavelength if desired, such as in a combined SLO and OCT system in which it may be desirable to use the same light source in order to reduce the cost and complexity of the system.
