Abstract
There is provided a speckle measurement apparatus to improve accuracy of flow velocity measurement or the like of particulates such as erythrocytes, the speckle measurement apparatus including an imager that captures scattered light images returned from an object to be measured when the object to be measured is irradiated with coherent light as speckle images, and a controller that determines a measurement area that is the same site of the object to be measured in a plurality of the speckle images captured continuously in time series by the imager by incorporating a displacement amount of a relative positional relationship between the object to be measured and the imager.
Claims6
A speckle measurement apparatus, comprising:
- an imager that captures scattered light images returned from an object to be measured when the object to be measured is irradiated with coherent light as speckle images;
- and
- a controller that determines a measurement area that is a same site of the object to be measured in a plurality of the speckle images captured continuously in time series by the imager by incorporating a displacement amount of a relative positional relationship between the object to be measured and the imager.
A speckle measurement method, comprising:
- irradiating an object to be measured with coherent light;
- capturing scattered light images returned from the object to be measured as speckle images;
- and
- determining by a controller a measurement area that is a same site of the object to be measured in a plurality of the speckle images captured continuously in time series by incorporating a displacement amount of a relative positional relationship between the object to be measured and an imager.
