摘要： An image generating methodology for displaying brain activation areas with improved accuracy in a living body light measurement system for generating an image of the changes in blood volume of the brain. A spatial intensity distribution of changes in blood volume can be generated by detecting brain activation in many sampling points, and a spatial interpolation process is executed on this data. A threshold process is executed on the distribution to extract the distribution of coordinates having a signal intensity of at least the predetermined threshold. The displacement between the brain activation area and the maximal location of the distribution is stored in a recording unit of the system in order to compensate for the distribution extracted by the threshold process. Accordingly, brain activation areas can be estimated with greater location accuracy, and the diagnosis and medial treatment for brain diseases can likewise be executed with greater accuracy.

摘要： In the past, comparison of mean values or variances measured from multiple subjects with one another has been a mainstream of diagnostic support to be achieved using cerebral activity signals. However, in this case, it is hard to absorb individual differences, and the precision in a diagnostic support technology is low. In order to improve the precision in the diagnostic support technology, the property of data acquired by an optical organism measurement system is utilized in order to create and display information representing a change in the condition of each person. Thus, diagnosis of each person is effectively supported. Measured light signals are used to calculate and record changes in the concentrations of oxidized hemoglobin (Hb), deoxidized Hb, and total Hb respectively. Based on each data (representing the Hb concentration changes), two or more Hb concentration changes (for example, the oxidized Hb concentration change and deoxidized Hb concentration change) are classified according to whether the changes are increases or decreases, and indicated in the form of symbols, an image, or a graph. Thus, an examining person is provided with compressed and simplified information and supported in diagnosis.

摘要： A wavelength selective switch for suppressing degradation of pass band characteristics when the temperature rises. The wavelength selective switch includes a spectroscopic element for separating input light and providing angular dispersion depending on wavelengths, a collective lens for gathering light output from the spectroscopic element, and a movable reflection block which includes a plurality of mirrors arranged in the direction of angular dispersion made by the spectroscopic element, changes the angles of the mirrors in a direction differing from the direction of angular dispersion, and reflects the light coming from the collective lens. The collective lens is fixed at one end with respect to the direction of angular dispersion, expands with heat in a direction in which it is not fixed when the temperature rises, and outputs the light in a direction opposite to the direction in which the angle of light output from the spectroscopic element changes.
