|1. (WO2017175470) SPECKLE MEASUREMENT DEVICE AND SPECKLE MEASUREMENT METHOD|
|Title:||SPECKLE MEASUREMENT DEVICE AND SPECKLE MEASUREMENT METHOD|
[Problem] To improve the accuracy of flow rate measurements and the like that target particles such as red blood cells. [Solution] This speckle measurement device comprises: an imaging unit that captures, as speckle images, images of scattered light returning from an object to be measured when the object to be measured is irradiated with coherent light; and a control unit that factors in movement in the relative positional relationship between the object to be measured and the imaging unit, and determines the measurement region corresponding to the same site of the object to be measured in a plurality of the speckle images captured continuously over time by the imaging unit.
