    "abstract": "The principle of the multiple-spark camera consists, as is well known, in obtaining a purely optical image separation by successive illumination of a series of spark gaps, thereby eliminating any mechanical movement. There are disadvantages: the parallax appearing with objects which are too far spread in depth; the necessity of additional provisions for self-luminous events; and the limited total number of images with the type of operation usually used today. This article reports on a new arrangement which eliminates this last disadvantage. The installation consists of five series each of 10 spark gaps, and 5 drums. The film on the respective drums is 25 cm wide and 1 m long so that, at a film speed of 100 m/sec and an image height of 2 cm, a maximum total of 2500 pictures of an event can be taken; 5000 can be taken at an image height of 1 cm. The picture frequency can be as high as 250,000/sec at 2 cm height and 500,000/sec at 1 cm height. An extremely large quantity of information can be recorded in a single run.",
