Patent ID: 7837328

Claim:
An optical image-measuring device having: a light source; an interference optical generator configured to split light that is emitted from said light source into a signal light directed toward a fundus oculi of an eye to be examined and a reference light directed toward a reference mirror, to generate an interference light by superimposing said signal light passed through said fundus oculi and said reference light reflected by said reference mirror; a detector configured to detect said interference light that is generated, an image generator configured to form tomographic images of said fundus oculi based on the detection results by said detector, wherein the optical image-measuring device comprises a storing part configured to store position information indicating a stationary position of said reference mirror based on previously formed said tomographic images; and a driving part configured to shift said reference mirror toward the optical path direction of said reference light to said stationary position of said reference mirror indicated by said position information related to said eye to be examined, which is stored in said storing part, wherein said driving part is configured to fix the position of said reference mirror after said reference mirror is moved to said stationary position indicated by said position information, and said image generator is configured to form said tomographic images of said fundus oculi for measurement depth of said fundus oculi determined from said stationary position of said reference mirror.
