摘要:
An optical system splits light into signal light and reference light and detects interference light between scattered light of signal light from living body and reference light. A scanner performs first scan in which first cross section that intersects interested blood vessel is repeatedly scanned with signal light. An image forming part forms first cross sectional image expressing chronological variation of morphology of first cross section and phase image expressing chronological variation of phase difference based on detection results of interference light acquired during first scan. A blood vessel region specifying part specifies blood vessel region corresponding to interested blood vessel for first cross sectional image and phase image. A blood flow information generator generates blood flow information related to interested blood vessel based on blood vessel region of first cross sectional image and chronological variation of phase difference within blood vessel region of phase image.
