- 5. Conclusions Single-exposure speckle photography can be used to produce a map of flow velocity distributions, in which velocity is coded as a variation in the variance (contrast) of the speckle pattern. Spatial filtering techniques can be used to enhance these photographs, by converting the variance variations to intensity variations.

- A photograph of a flow field is taken under laser illumination. If the exposure is short enough, the velocity distribution in the field will be mapped on the photograph as variations in speckle contrast. These contrast variations can be converted to intensity variations by means of a simple spatial filtering technique, to give a direct picture of the velocity distribution in the flow field.

- We present the preliminary findings of an investigation into the visualization of retinal blood-flow distribution by means of single-exposure laser-speckle photography. The technique relies on the speckle effect produced when laser light is scattered at a diffusing surface and on the fact that the speckle will be averaged out to some extent when the surface concerned is moving.
