摘要：An optical device for in vivo, non-invasive measurement of changes in

hemoglobin concentration associated with activities of the cerebral function is provided.The device comprises a light source and a light detector (12) for irradiating light into aliving body (11) and detecting scattered light having passed through the living body, astimulus device (15) to intermittently present a stimulus to the subject and a noisedetection system to detect noise associated with body movement of the subject fromthe detected scattered light signal. If body movement is detected during a measurementperiod the detected signal is discarded from further processing and a feedback is givento the stimulus device to repeat or adapt the presentation of the stimulus.
