Abstract
<p> Blood flow is important biological information, and noninvasive and highly accurate blood flow measurement has been required. The blood flow measurement method using near infrared light and visible light has little influence on the human body, so it can be expected to be applied to daily health management. Speckle is one of the measurement methods using light, there are studies on the measurement of the flow velocity and estimation of the static layer thickness corresponding to the blood vessel depth using laser speckle. If it is possible to estimate the fluid layer thickness corresponding to the blood vessel thickness, important biological information such as occlusion of the blood vessel can be obtained. Therefore, in this research, a method to estimate fluid layer thickness and flow velocity simultaneously by laser speckle was proposed. In this paper, as a basic study, we measured the speckle pattern generated in the specimen simulating skin and blood vessel, and investigated the possibility of simultaneous estimation of fluid layer thickness and flow velocity by laser speckle.</p>
