ABSTRACT OF THE DISCLOSURE In a tissue metabolism measuring apparatus, light sources (31 to 33) emit rays of different wavelengths; the rays are branched as reference light pulses and sample light pulses through optical fibers (38 and 39); the sample light pulses are transmitted through a living body to be examined; the reference light pulses are delayed by means of mirrors (48 to 50); the sample light pulses transmitted through the living body and the delayed reference light pulses are collected by a lens (44); based on the collected light, a second harmonic of the light is generated by an optical crystal (45); and the second harmonic enters a photomultiplier (51). A photon counter 52 counts photons based on the output of the photomultiplier and calculates an average value of the count output. Further, a delay amount of the reference light pulses is changed and when the delay amount of the reference light pulses with respect to the sample light pulses transmitted through the living body is a predetermined value, the average value of the count output of photons of the second harmonic is determined. Thus, scattered components of the transmitted beam in the living body can be removed based on the average value.
