摘要:
The present technology relates to a measurement apparatus and a measurement method that realize reduction in power consumption while at the same time ensuring reduction in cost. Provided is a measurement apparatus that includes a light source, a light reception section, and a measurement section. The light source emits at least partially coherent light. The light reception section receives the light emitted from the light source by way of a measurement target and detects a signal proportional to the received light. The measurement section measures the number of oscillations included in the signal detected by the light reception section within a certain time period. For example, the present technology can be applied to a measurement apparatus measuring a blood flow of a human body.
