Adaptive optics allows one to overcome the limitations imposed by the optics of the eye on the resolution of images obtained with scanning laser ophthalmoscopes. However, since the image is obtained by scanning at a frame rate of typically 10-20 Hz, involuntary eye movements become a non-negligible limitation when the field covered by a single frame decreases and a higher resolution is sought. This in turn has a negative influence on image alignment and the necessary summation process to enhance the overall signal-to-noise ratio, as well as on further processing techniques such as deconvolution. Hardware solutions have been investigated but they rely typically on complex set-ups. For this reason, relatively simple software solutions have usually been implemented.
