摘要: According to the present invention, a measurement method for visualizing the flow of a fluid (23) has: a preparation step for dissolving, in the fluid (23), a photochromic compound of which the amount of light absorption changes when the photochromic compound is irradiated with a transformation-generating light (31); a transformation-generating light irradiating step for irradiating the fluid (23) with the transformation-generating light (31) that causes photochromism; and a post-transformation image capturing step for capturing an image of the fluid (23) irradiated with the transformation-generating light. In the post-transformation image capturing step, a first image (B) is generated by capturing the image of the fluid (23) using first light in a first wavelength range, wherein the amount of light absorption of the first light changes due to the irradiation of the transformation-generating light (31).
