Blood flow measurement device

Abstract

Provided is a blood flow measurement device having excellent measurement accuracy. The blood flow measurement device includes a light source unit that irradiates an object with near-infrared rays, and a light receiving section that receives scattered light generated by scattering of the near-infrared rays emitted from the light source unit by the object, the blood flow measurement device further including a first polarizing element that is disposed on a front surface of the light source unit, includes a layer formed of a liquid crystal compound, and changes a polarization state of the near-infrared rays, and a second polarizing element that is disposed on a front surface of the light receiving section, includes a layer formed of a liquid crystal compound, and changes a polarization state of the near-infrared rays.
