Abstract: An ophthalmic scanning system includes a first imaging modality, a second imaging modality different from the first imaging modality, and a control system that maps the first imaging modality to the second imaging modality by compensating for at least one of an optical-mechanical and an electro-mechanical projection difference between the first and second imaging modalities. The control system provides a scan location for the second imaging modality based on a scan location of the first imaging modality.

Abstract: A technique for generating a mapping relating values of a scan parameter of an ocular imaging apparatus that are indicative of scan locations in an eye at which the apparatus acquires digital images of imaged regions of the eye, to respective values of a conversion factor for calculating a distance between designated ocular features in the imaged regions, by: simulating light ray propagation to relate each value of the scan parameter in a sequence of scan parameter values to a corresponding location in a model eye; calculating, for each scan parameter value, a distance between the corresponding location in the model eye and a location in the model eye corresponding to an adjacent value in the sequence; and using the calculated distances to generate a respective value of the conversion factor for each scan parameter value.
