We present an optical imaging system, called "optical echography", which provides longitudinal slices of a biological sample directly and at video-rate. The apparatus, based on a femtosecond laser light source, employs the property of time-to-space conversion of a single-shot correlator in order to image in vivo biological tissues with a depth resolution of 10 micrometers.
