Abstract

A method for detection of absorbing objects embedded in scattering media is described. In a confocal imaging arrangement the sample is illuminated with light modulated in polarization. The modulated part of the transmitted light is detected with lock-in-technique. Under the condition that the scattering particles are smaller than the wavelength, this method is able to supply images with higher resolution and contrast than conventional transillumination.
