Retinal Imaging of Low Light Signals
This technology enables high resolution in vivo images of the retina by a technique of simultaneous image capture and dual registration, which corrects for the natural movement of the living eye to enable many imaging frames to be combined to increase the signal to noise ratio from very weak signals, such as those from fluorescence or phase imaging,...

Metrics to Predict the Subjective Impact of the Eye's Wave Aberration
A vision quality metric is an algorithm which interprets the complex wavefront measurements of the aberrations in a human eye in a way which reflects the subjective perception of vision quality. ApplicationsThe vision quality metric is to be used with a wavefront aberrometer to calculate a description of the quality of vision. This metric can serve...
