Disclosed is a method for measuring light in a living body and capable of discriminating the size in activation brain areas. Two diamond-shaped probes alternately installed spatially for a light source or a light detector, and a second light source or light detector are installed between a first light source or light detector and an image is reconstructed utilizing all the sampling points, and whether or not the largest position on the reconstructed image is in proximity to the first or the second sampling point is determined, and an image is reconstructed from those results using only the position information from the first or the second sampling point. The difference in the sizes of the activation brain area can be displayed as an image, and an increased amount of information can be acquired from results measuring the metabolic substance concentration within a living body.
