Abstract
A measurement method for visualizing the flow of a fluid that includes: a preparation process where a photochromic compound, whose amount of absorption of light changes upon irradiation with transformation-inducing light, is dissolved in the fluid; a transformation-inducing irradiation process where the fluid is irradiated with transformation-inducing light that causes photochromism; and a post-transformation imaging process where an image of the fluid is taken after irradiation by the transformation-inducing light. During the post-transformation imaging process, a first image is generated by taking an image of the fluid by using first light in the first wavelength range in which the amount of absorption of light changes upon irradiation with transformation-inducing light.
