Abstract
After a brief discussion of the limiting factors in streak record information, a test method is described with which the influence of mirror distortion and air turbulence on the time resolution can be studied. Results for 1×2 in. beryllium and steel rotating mirrors are given. The time resolution of a streak camera equipped with a beryllium mirror is found to be a few nanoseconds when the instrument is used as a chronometer; velocity measurements can be carried out with over‐all accuracies of a few tenths of a percent.
