ABSTRACT:
An optical measurement apparatus for a living body having light transmitting elements for transmitting light to a plurality of positions in areas to be examined within a living body detects light which has been transmitted by the light transmitting elements after passing through the living body at a plurality of positions in the examination area; applies to the living body a load to which the living body responds; calculates signals representing an intensity change of the transillumination detected by the detecting the light at the measuring points based on the positional relation between each light transmitting position and light detecting position when a load is applied to the living body and when a load is not applied; calculates time variations of one signal among two signals calculated at the measuring points based on said positional relation; and displays graphs of the above-calculated signals in correspondence with said positional relation.
