<p>A biological optical measuring instrument such that a subject is irradiated with light, the transmitted light is picked up, an optical signal thus generated is processed, and a biological change in a predetermined portion of the subject is displayed. Optical signals in sections of predetermined time lengths are extracted from the optical signal generated along the time axis, section data is created from the extracted optical signals, the average of the created section data is calculated, an optical signal section containing the noise component is located on the basis of the differential coefficient of the extracted optical signal prior to the creation of average section data of predetermined time lengths, the section data on the optical signal containing the noise component is excluded from the averaging, and thus the section data containing the noise component is automatically removed from biological optical measurement data by calculation, not by visual operation. In such a way, a measurement result with high reliability is quickly obtained and displayed.</p> |
