PROBLEM TO BE SOLVED: To provide technique allowing high-accuracy blood flow measurement.SOLUTION: An optical image measurement system includes an optical system, a scanning part, an image formation part, a blood vessel region specific part, and a blood flow information generation part. The optical system divides light from a light source into signal light and reference light, and detects interference light between the scattered light of the signal light by a living body and the reference light passing through a reference light path. The scanning part performs first scanning repeatedly scanning a first cross-section crossing a notice blood vessel of the living body by the signal light. The image formation part forms a first tomographic image representing a time-series change of a form in the first cross-section and a phase image representing a time-series change of a phase difference, based on a detection result of the interference light obtained by the optical system in the first scanning. The blood vessel region specific part specifies a blood vessel region corresponding to the notice blood vessel about each of the first tomographic image and the phase image. The blood flow information generation part generates blood vessel information related to the notice blood vessel based on the blood vessel region of the first tomographic image and the time-series change of the phase difference in the blood vessel region of the phase image. |
