High speed single charge coupled device Cranz-Schardin camera

Résumé

This article describes an ultrahigh speed visualization system based on a miniaturization of the Cranz-Schardin principle. It uses a set of high power light emitting diodes (LEDs) (Golden Dragon) as the light source and a highly sensitive charge coupled device (CCD) camera for reception. Each LED is fired in sequence and images the refraction index variation between two relay lenses, on a partial region of a CCD image sensor. The originality of this system consists in achieving several images on a single CCD during a frame time. The number of images is 4. The time interval between successive firings determines the speed of the imaging system. This time lies from 100 ns to 10 µs. The light pulse duration lies from 100 ns to 10 µs. The principle and the optical and electronic parts of such a system are described. As an example, some images of acoustic waves propagating in water are presented
