Abstract
Optical extinction in mammalian tissues is measured at 633 nm by using
heterodyne detection. Its sensitivity, directivity and signal to nois
e ratio allow to detect coherent photons after attenuation up to 10 op
tical densities. This method permits us to detect unscattered photons
passing through more than 5 mm of different tissues such as : muscle,
skin and liver.
