Scanning ophthalmoscope with spatial light modulators

摘要

A scanning ophthalmoscope scans an object plane in the interior of the eye by employing a first spatial light modulator to generate a time-varying first modulation pattern. A second spatial light modulator receives the illumination field generated by the interaction of the first modulation pattern with the interior of the eye. The second spatial light modulator generates a second modulation pattern corresponding to the first modulation pattern and transmits this second modulation pattern to an image detector, thereby forming an image of the object plane in the interior of the eye. The first and second spatial light modulators are linked by a function or mapping such that a modulation pattern generated by the first spatial light modulator maps to a particular modulation pattern generated by the second spatial light modulator.
