We present a dual wavelength endoscope which uses Endoscopic Laser Speckle Contrast Analysis (ELASCA) with the aim to image tissue blood flow and perfusion during surgical procedures. In this study we measure speckle decorelation times, which are ass

In this paper, we briefly review our work on low-coherence photorefractive holography and report on the current state of the art. We present what is, to the best of our knowledge, the fastest-ever three-dimensional (3-D) imaging system and present re

We report on imaging through solid scattering media with photorefractive holography using sources of low temporal and spatial coherence. Holograms were recorded through samples of moderate thickness by using low-cost light-emitting diodes. The reduct

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 demonstrate an application of light-emitting diodes to photorefractive holography with multiple-quantum-well devices. Holograms corresponding to three-dimensional images with a depth resolution of less than 10 μm were recorded, with image acquisi

When imaging through scattering media it is easiest to visualise a pulse propagating through the material. As the light propagates it is scattered away from its original trajectory and it becomes diffuse, both spatially and temporally. It is importan

Wide-field low coherence photorefractive holography has the potential to acquire depth-resolved images at up to 1000 frames/second, including through scattering media. We have applied it to microscopy using a diverse range of light sources.
