TRENDS IN OPTICAL BIOMEDICAL IMAGING

Recent progress in the development of optical techniques for non-invas ive imaging in biology and medicine is reviewed. We start with some fu ndamental considerations of light propagation in random media. We then discuss imaging using coherent unscattered light and diffuse light. M icroscopic techniques based on one-and two-photon fluorescence are des cribed and several types of nonlinear and time-resolved microscopy are explained. We conclude with some application examples and an outlook.
