Title:
BLOOD FLOW MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/179345
Kind Code:
A1
Abstract:
Provided is a blood flow measurement device that is provided with at least one AD conversion unit and processes a plurality of reflection light signals. The blood flow measurement device is provided with at least one light source unit, a plurality of light receiving units, a plurality of signal processing units, at least one multiplexing unit, and at least one AD conversion unit. The light source unit emits coherent light to a living body. Each of the plurality of light receiving units receives reflection light of the coherent light and converts the intensity of the reflection light into a current signal. Each of the plurality of signal processing units converts the current signal into a voltage signal. The multiplexing unit multiplexes a plurality of voltage signals into at least one multiplexed voltage signal. The AD conversion unit samples the multiplexed voltage signal and acquires a multiplexed digital signal.
