BIOLOGICAL LIGHT MEASUREMENT RESULT ANALYSIS APPARATUS, INQUIRY SYSTEM USING THE SAME, AND BIOLOGICAL LIGHT MEASUREMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an apparatus capable of providing a subject's fatigue state, as a more accurate index, by using a signal obtained using biological light measurement.SOLUTION: An inquiry system comprises: a biological light measurement apparatus for measuring hemoglobin variations at a plurality of measurement points on a subject's head; an analysis apparatus for analyzing a biological light measurement result obtained by measurement of the biological light measurement apparatus; a display apparatus for displaying a result of analysis by the analysis apparatus; and an input apparatus for inputting information required for the analysis to the analysis apparatus. The analysis apparatus comprises a correlation determination unit that, by using hemoglobin variation waveforms obtained using the biological light measurement, calculates correlation between hemoglobin variation waveforms at the plurality of measurement points and counts the number of combinations of measurement points that have been determined to correlate with each other.SELECTED DRAWING: Figure 8
