%X In the present report, I introduce our recent research about non-staining blood flow imaging of Japanese medaka fish egg (Oryzias latipes) using an imaging-type two-dimensional Fourier spectroscopic system. Due to optical interference caused by optical path differences and light frequency shifts that were given by a partial movable mirror and Doppler effect, respectively, molecular vibration and heart beat signals can be simultaneously obtained in vivo. Therefore, non-staining blood flow images were successfully obtained by plotting light intensities associated with the heart beat, and molecular distributions of O¨CH (water) and C¨CH (hydrocarbons or aliphatic compounds) were visualized without staining. I additionally discuss about future applications of the imaging system to biological and biomedical research
