Based on the classical optical coherence theory, ghost imaging with twisted Gaussian Schell-model (GSM) beams is analyzed. It is found that the twist phase of the GSM beam has strong influence on ghost imaging. As the absolute value of the twist factor increases, the ghost image disappears gradually, but its visibility increases. This phenomenon is caused by the fact that the twist phase enhanc...

Two fluorescent brighteners were used to stain an isolate of Bacillus cereus var. mycoides and soil pseudomonad. The stained organisms were fractionated by two procedures to determine which cellular constituents were reacting with the brighteners. Both fractionation procedures provided evidence that the brighteners were adsorbed to proteins within the cells. Microscopy examination of ghost c...

We present an experimental comparison between different iterative ghost imaging algorithms. Our experimental setup utilizes a spatial light modulator for generating known random light fields to illuminate a partially-transmissive object. We adapt the weighting factor used in the traditional ghost imaging algorithm to account for changes in the efficiency of the generated light field. We show th...
