Title:
BLOOD FLOW MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/085221
Kind Code:
A1
Abstract:
Provided is a blood flow measurement device exhibiting excellent measurement accuracy. The blood flow measurement device comprises: a light source unit that projects near-infrared radiation onto an object; and a light-receiving unit that receives scattered light resulting from the near-infrared radiation emitted from the light source unit being scattered by the object. The blood flow measurement device further comprises: a first polarizing element that is disposed on a front surface of the light source unit, that includes a layer formed of a liquid crystal compound, and that changes the polarization state of the near-infrared radiation; and a second polarizing element that is disposed on a front surface of the light-receiving unit, that includes a layer formed of a liquid crystal compound, and that changes the polarization state of the near-infrared radiation.
