Cathode Ray Photography of Random Electrical Transients

Nature volume 131, pages 620621 (29 April 1933) | Download Citation



THE recent improvements in the design of cathode ray oscillographs have naturally led to an exploration of their use for the external photographic recording of recurrent electrical events and also those of a transient nature which occur at random intervals. In the case of recurrent phenomena, such photo graphy of the cathode ray trace is easy, but for random transients a satisfactory method must ensure that no event is missed and that fruitless exposures are few.
