Abstract:
1. An optical image measuring device that forms tomographic images of at least a first depth zone and a second depth zone of a measured object, respectively, comprising: a splitting part configured to split a light from a light source into a signal light and a reference light; a first light path configured to be capable of adjusting an optical path length of said reference light to an optical path length that corresponds to said first depth zone; a second light path configured to be capable of adjusting an optical path length of said reference light to an optical path length that corresponds to said second depth zone; an optical system comprising an objective lens and a focusing lens, and configured to illuminate said measured object with said signal light; an optical system comprising an objective lens and a focusing lens, and configured to condense said signal light into said first depth zone; an interference light generation part configured to generate an interference light by causing interference with said signal light reflected from said first depth zone and said reference light via said first light and generate an interference light by causing interference with said signal light reflected from said second depth zone and said reference light via said second light path; a detecting part configured to detect each of the interference light corresponding to said first depth zone and the interference light corresponding to said second depth zone; and an image forming part configured to form tomographic images of said first depth zone and said second depth zone, respectively, based on the detection by said detecting part.
