摘要： An optical system calibration system and method particularly suited for calibrating the optical slit planes in an ophthalmic diagnostic instrument. The system includes an illumination source projector, an illumination image receiver, and a calibration component all having known relative positions, orientations and physical and optical characteristics. The calibration component includes at least two separated, diffusely reflecting surfaces. Images of an exemplary slit illumination pattern projected onto the calibration component and formed on the diffusely reflecting surfaces are detected by the image receiver such as a video camera. Based upon camera image coordinates and triangulation parameters of the projector, the receiver, and the calibration component, the slit image positions on the image detector plane can be calibrated to the axially displaced, diffusely reflecting calibration component surface positions.
