   Abstract:
   In this work, we develop and evaluate the photoacoustic technique for recording spectra of white and gray mammalian brain tissues. In additional to the experimental work, we also discuss the geometric aspects of photoacoustic signal generation using collimated light. Spectra constructed from the peak-to-peak amplitude of the photoacoustic waveforms indicate differences in the two tissue types at wavelengths between 620 and 695 nm. The potential of the technique for non-invasive diagnosis is discussed.
