Speed camera, computer artwork. This piece of equipment is used to photograph vehicles exceeding the local speed limit. As well as a camera, each unit also includes an electronic flash that is used at night. The camera measures a vehicle's speed using either piezoelectric strips embedded in the road, or high frequency radio waves. The photograph taken shows the number plate of the vehicle and has details encoded on the frame (time, date, location and speed). The film is recovered and processed at regular intervals, and notices are issued to drivers. As of 1993, the photograph is admissible as evidence in the case of disputed offences.
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
