Abstract:
An ocular fundus camera system and an associated methodology. The system includes (a) an image sensor disposed along a fundus-image reflection path adjacent that path's downstream end, and in optical communication with light carried in this path, (b) an aperture centered on the reflection path's long axis, operatively associated with, and stationary with respect to, the sensor at a location which is upstream from the sensor, and (c), for accomplishing (1) precision fundus-image focusing on the sensor, and additionally (2) autorefraction, optical, light-content shifting structure, operable selectively for producing, within that portion of the reflection path which is disposed downstream from the shifting structure, relative trans-axial displacement solely of any non-collimated light carried in that portion of the main path which is disposed upstream from the shifting structure.
