We report the development of a whole-field fluorescence lifetime imaging (FLIM) system with high temporal resolution based on a time-gated image intensifier. The optimized temporal gate width is < 100 ps, and changes in the environment of a fluoresce

We discuss a real-time coherence gated three-dimensional (3-D) imaging system, based on photorefractive holography with ultrashort pulses, which has been applied to imaging through turbid media with a view to developing biomedical instrumentation. Su

We report on time-gated holographic imaging at 450 nm using photorefractive media to achieve high depth and transverse resolution through a turbid medium. Using 70 fs pulses from a frequency-doubled mode-locked Ti: sapphire, we have demonstrated that

An experimental and theoretical investigation of the temporal spread of an ultrashort light pulse on transmission through a highly scattering medium has been made. For the strongly diffuse light, the transmitted pulse may be described by a universal

Fluorescence lifetime imaging (FLIM) can provide noninvasive functional/diagnostic imaging by exploiting the sensitivity of fluorescence lifetime to the environmental changes in, for example, ion concentration (e.g., Ca2+), and pH [e.g., Refs. 1 and
