SCATTERER MEASUREMENT METHOD AND SCATTERER MEASUREMENT DEVICE

摘要

A scatterer measurement method according to an aspect of the present invention includes: applying first irradiation light passing through a first space in which scatterers are present; receiving first scattered light generated as a result of scattering of the first irradiation light by the scatterers; applying, after the scatterers have moved from the first space to a second space at least partially different from the first space, second irradiation light passing through the second space; receiving second scattered light generated as a result of scattering of the second irradiation light by the scatterers; and calculating the speed of the scatterers on the basis of a difference between a first time point when the first scattered light is received and a second time point when the second scattered light is received and the moving distance of the scatterers from the first time point to the second time point.
