BLOOD FLOW MEASURING DEVICE

Abstract:

Provided is a blood flow measuring device that is provided with at least one AD conversion unit and processes a plurality of reflected light signals. Provided is a blood flow measuring device provided with at least one light source unit, a plurality of light reception units, a plurality of signal processing units, at least one multiplexing unit, and at least one AD conversion unit, in which the light source unit irradiates a living body with coherent light, each of the plurality of light reception units receives reflected light of the coherent light and converts intensity of the reflected 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, and the AD conversion unit samples the multiplexed voltage signal to obtain a multiplexed digital signal.
