- 摘要：
PROBLEM TO BE SOLVED: To operate a tomography at the same site imaged last time accurately and smoothly.
SOLUTION: An ophthalmological imaging apparatus comprises: an interference optical system having a scanning means for scanning a measuring light emitted from a light source on a predetermined site of a test eye, and for obtaining a tomographic image of the predetermined site of the test eye an observation optical system for obtaining a front image of the predetermined site and a setting means for setting the scanning position of the measuring light by the scanning means. The apparatus includes: a memory means for memorizing the past tomographic image, the scanning position information of the past measuring light, and the front image obtained to respond to the tomographic image a detecting means for detecting a displacement of the present image to the past image a correcting means for obtaining the scanning position information by the memory means and correcting the scanning position information based on the detected displacement direction and the displacement amount and a determination means for sequentially detecting a displacement amount of the scanning position between the present scanning position information and the scanning position information after the above correction, and determining whether the displacement amount is satisfied within the predetermined tolerance level or not.
