Abstract:
1. An optical measurement apparatus for living body comprising a means for irradiating visible to infrared light onto an object to be examined, a means for detecting light transmitted inside said object and generates signals corresponding to the detected amount of light, a signal processing means for processing the signals and generating biological signals of the object to be examined and a display means for displaying the biological signals generated by said signal processing means; wherein said signal processing means comprises at least one signal separating means for separating the biological signals into multiple component signals, a signal selecting means for selecting specified component signals based on correlation values between component signals and a pre-determined reference waveform signal that represents a characteristic of living-body reaction of the examined object, and a signal reconstruction means for reconstructing the biological signals by using the selected specified component signals, excluding those containing noise, of said multiple component signals.
