    "abstract": "We present the theoretical and detailed experimental characterizations of\nPhotothermal Heterodyne Imaging. An analytical expression of the photothermal\nheterodyne signal is derived using the theory of light scattering from a\nfluctuating medium. The amplitudes of the signals detected in the backward and\nforward configurations are compared and their frequency dependences are\nstudied. The application of the Photothermal Heterodyne detection technique to\nthe absorption spectroscopy of individual gold nanoparticles is discussed and\nthe detection of small individual silver nanoparticles is demonstrated.",
