Abstract
An OCT imaging method of some exemplary aspects includes acquiring a first three dimensional data set by applying an OCT scan targeting a first three dimensional region of a sample, creating a first two dimensional map based on representative intensity values respectively of a plurality of pieces of A-scan data included in the first three dimensional data set, designating a second three dimensional region of the sample based on the first two dimensional map, acquiring a second three dimensional data set by applying an OCT scan targeting the second three dimensional region, and generating image data from at least part of the second three dimensional data set.
