DISPERSION OF PHOTON DENSITY WAVES IN SEA WATER
The frequency dependences of phase and group velocities speeds of photon density waves in an anisotropic scattering turbid medium of type of sea water are investigated. It is shown that such medium possesses an abnormal dispersion in relation to these waves. The possibility of time focusing of photon density waves is considered at linear frequency modulation of a radiated impulse. It is shown that full compression of a high-frequency component of an impulse is not achievable owing to frequency dependence of attenuation. The estimations of compression degree are executed at various parameters of a modulating signal.
